Description

UV RADIATION ADSORBING GLASS COMPOSITIONS, ARTICLES, AND METHODS OF MAKING THE SAMETECHNICAL FIELD[1] The present invention generally relates to UV radiation adsorbing glass compositions, glass articles comprising the same, and methods of making the same.BACKGROUND[2] Humans learned how to manufacture glass articles more than 5,000 years ago. The modern utility of glass is very diverse and includes both commercial and consumer use. Glass is commonly used for commodity applications and technological applications related to the automotive industry, electronic industry, spectroscopy, and the like. Often glass articles are also exposed to various environments, and to ensure the article's durability in the long term, glass compositions need to be designed to withstand such environments. For example, glass articles such as container glasses, flat glasses for windows, automotive windshields, laser host materials, fibers, tubing, and the like, are employed in both commodity applications such as bottles, vases, art and craft glass objects, architectural windows, automotive windshields, and the like as well as technological applications such as glass tubing, glass fibers, laser host materials, and the like, often endure the environmental attack of moisture and can lose their initial properties as a result. In addition, glass containers are often used for keeping items that can be sensitive to UV radiation, and therefore it is important to form glass containers that could block the transmission of this radiation that could otherwise affect the quality or performance of the items placed in the containers.[3] There is a need to develop commercially viable low-UV ray transmitting glass compositions on the grounds of cost and workability of the glass melt. However, the addition of UV radiation absorbing oxides to soda-lime-silica glass imparts undesired colour tint. Thus, there is a need for fairly neutrally-coloured and high- visible light transmittive glass articles containing substantially lower amounts of chemical or physical decolorizers than are typically required for decolourization oflow- UV ray transmitting container glasses. If desired, lightly tinted and high-visible light-transmissive glass articles can be produced.[4] These needs and other needs are at least partially satisfied by the present disclosure.SUMMARY[5] In various aspects, the present disclosure relates to a glass comprising: from about 0.09 to about 1.00 wt% of cerium oxide; from about 0.01 to less than 0.25 wt% of iron oxide; from about 0.01 to about 2.0 wt% of zinc oxide; greater than 0 wt% to about 0.1 wt% of titanium oxide, and wherein the glass is substantially free of erbium.[6] While yet in other aspects, when the glass is a soda-lime composition further comprising: from about 65 to about 75 wt% of SiC ; from about 8 to about 20 wt% of Na2<D; from 0 to about 15 wt% of CaO; from 0 to about 10 % of MgO; from 0 to about 5 wt % of AI2O3; from 0 to about 3 wt% of B2O3; from 0 to about 3 wt% of K2O; and from 0 to about 1 wt% of U2O. I n still further aspects, the glass is a soda- lime-silica type composition.[7] In still further, the glass disclosed herein exhibits transmission of less than about 45% in a wavelength range from about 300 to about 380 nm. While in still further aspects, the glass exhibits transmission equal to or greater than about 80% in a wavelength range from greater than about 380 nm to about 780 nm. In still further aspects, the glass is substantially colorless.[8] Also disclosed herein is an article comprising any of the disclosed herein glasses. In still further aspects, the article can comprise foodware, tableware, hollowware, jars, optical fibers, hollow fibers, lab-usable containers, art and craft glass objects, or any combination thereof.[9] Also disclosed herein is an article comprising a glass comprising: from about 0.09 to about 1 .00 wt% of cerium oxide; from about 0.01 to less than 0.25 wt% of iron oxide; from about 0.01 to about 2.0 wt% of zinc oxide; greater than 0wt% to about 0.1 wt% of titanium oxide, and wherein the glass is substantially free of erbium.

[0010] Also disclosed herein are methods comprising: a) providing: from about 65 to about 75 wt% of SiC>2; from about 8 to about 20 wt% of Na2<D; from 0 to about 15 wt% of CaO; from 0 to about 10 % of MgO; from 0 to about 5 wt % of AI2O3; from 0 to about 3 wt% of B2O3; from 0 to about 3 wt% of K2O; from 0 to about 1 wt% of U2O; from about 0.09 to about 1.00 wt% of cerium oxide; from about 0.01 to about 0.25 wt% of iron oxide; from about 0.01 to about 2.0 wt% of zinc oxide; and great than 0 wt% to less than about 0.08 wt% of titanium oxide; b) forming a homogeneous mixture; c) melting the mixture at a temperature from about 1 ,400 °C to about 1 ,500 °C for a first time to form a melted mixture, and d) forming any of the disclosed herein glasses, wherein the glass is substantially free of erbium.

[0016] The present invention can be understood more readily by reference to the following detailed description, examples, drawings, and claims, and their previous and following description. However, before the present articles, systems, and / or methods are disclosed and described, it is to be understood that this invention is not limited to the specific or exemplary aspects of articles, systems, and / or methods disclosed unless otherwise specified, as such can, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only and is not intended to be limiting.

[0017] The following description of the invention is provided as an enabling teaching of the invention in its best, currently known aspect. To this end, those skilled in the relevant art will recognize and appreciate that many changes can be made to the various aspects of the invention described herein while still obtaining the beneficial results of the present invention. It will also be apparent that some of the desired benefits of the present invention can be obtained by selecting some of the features of the present invention without utilizing other features. Accordingly, those of ordinary skill in the pertinent art will recognize that many modifications and adaptations to the present invention are possible and may even be desirable in certain circumstances and are a part of the present invention. Thus, the following description is again provided as illustrative of the principles of the present invention and not in limitation thereof.DEFINITIONS

[0018] As used herein, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to an “article” includes aspects having two or more such articles unless the context clearly indicates otherwise.

[0019] It is appreciated that certain features of the disclosure, which are, for clarity, described in the context of separate aspects, can also be provided in combination in a single aspect. Conversely, various features of the disclosure,which are, for brevity, described in the context of a single aspect, can also be provided separately or in any suitable combination.

[0020] As used herein, the terms “optional” or “optionally” mean that the subsequently described event or circumstance may or may not occur, and that the description includes instances where said event or circumstance occurs and instances where it does not.

[0021] It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only and is not intended to be limiting. As used in the specification and in the claims, the term “comprising” can include the aspects “consisting of” and “consisting essentially of.” Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. In this specification and in the claims, which follow, reference will be made to a number of terms that shall be defined herein.

[0022] For the terms "for example" and "such as" and grammatical equivalences thereof, the phrase "and without limitation" is understood to follow unless explicitly stated otherwise.

[0023] Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the disclosure are approximations, the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical value, however, inherently contains certain errors necessarily resulting from the standard deviation found in their respective testing measurements. Furthermore, when numerical ranges of varying scope are set forth herein, it is contemplated that any combination of these values inclusive of the recited values may be used. Further, ranges can be expressed herein as from “about” one particular value and / or to “about” another particular value. When such a range is expressed, another aspect includes from the one particular value and / or to the other particular value.

[0024] Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another aspect. It will be further understood that the endpoints of each of the ranges aresignificant both in relation to the other endpoint and independently of the other endpoint. Unless stated otherwise, the term “about” means within 5% (e.g., within 2% or 1%) of the particular value modified by the term “about.”

[0025] Throughout this disclosure, various aspects of the invention can be presented in a range format. It should be understood that the description in range format is merely for convenience and brevity and should not be construed as an inflexible limitation on the scope of the invention. Accordingly, the description of a range should be considered to have specifically disclosed all the possible subranges as well as individual numerical values within that range. For example, a description of a range such as from 1 to 6 should be considered to have specifically disclosed subranges such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., as well as individual numbers within that range, for example, 1 , 2, 2.7, 3, 4, 5, 5.3, 6 and any whole and partial increments therebetween. This applies regardless of the breadth of the range.

[0026] As used herein, the term “composition” is intended to encompass a product comprising the specified ingredients in the specified amounts, as well as any product which results, directly or indirectly, from a combination of the specified ingredients in the specified amounts. It is understood that the term “glass composition,” as disclosed herein, refers to a glass that was melted to form a defined composition but before it was formed into a specific glass article. It is further understood that the glass composition as used herein is not the same as batch ingredients that were introduced into the mix before forming the glass. In some aspects, the batch ingredients used to form the composition can comprise elements that the glass composition is substantially free of.

[0027] A weight percent (wt.%) of a component, unless specifically stated to the contrary, is based on the total weight of the formulation or composition in which the component is included.

[0028] As used herein, the term "substantially" means that the subsequently described event or circumstance completely occurs or that the subsequently described event or circumstance generally, typically, or approximately occurs.

[0029] Still further, the term “substantially” can refer to at least about 80 %, at least about 85 %, at least about 90 %, at least about 91 %, at least about 92 %, at least about 93 %, at least about 94 %, at least about 95 %, at least about 96 %, at least about 97 %, at least about 98 %, at least about 99 %, or about 100 % of the stated property, component, composition, or other condition for which substantially is used to characterize or otherwise quantify an amount.

[0030] In other aspects, as used herein, the term “substantially free,” when used in the context of a composition or component of a composition that is substantially absent, is intended to indicate that the recited component is not intentionally batched and added to the composition but can be present as an impurity along with other components being added to the composition. In such aspects, the term “substantially free” is intended to refer to trace amounts that can be present in the batched components, for example, it can be present in an amount that is less than about 1 % by weight, e.g., less than about 0.5 % by weight, less than about 0.1 % by weight, less than about 0.05 % by weight, or less than about 0.01 % by weight of the stated material, based on the total weight of the composition.

[0031] As used herein, the term “substantially,” in, for example, the context “substantially identical” or “substantially similar,” refers to a method or a system, or a component that is at least about 90%, at least about 91%, at least about 92%, at least about 93%, at least about 94%, at least about 95%, at least about 96%, at least about 97%, at least about 98%, at least about 99%, or about 100% by similar to the method, system, or the component it is compared to.

[0032] As used herein, the term “melting point” refers to a temperature at which the batch materials fully melt to obtain a homogeneous liquid. By glass industry convention, the melting point occurs at a liquid viscosity of around 10Pa-s.

[0033] While aspects of the present invention can be described and claimed in a particular statutory class, such as the system statutory class, this is for convenience only and one of ordinary skill in the art will understand that each aspect of the present invention can be described and claimed in any statutory class. Unless otherwise expressly stated, it is in no way intended that any method or aspect set forth herein be construed as requiring that its steps be performed in a specificorder. Accordingly, where a method claim does not specifically state in the claims or descriptions that the steps are to be limited to a specific order, it is in no way intended that an order be inferred in any respect. This holds for any possible nonexpress basis for interpretation, including matters of logic with respect to the arrangement of steps or operational flow, plain meaning derived from grammatical organization or punctuation, or the number or type of aspects described in the specification.

[0034] The present invention may be understood more readily by reference to the following detailed description of various aspects of the invention and the examples included therein and to the Figures and their previous and following description.

[0088] The following examples are put forth so as to provide those of ordinary skill in the art with a complete disclosure and description of how the compounds, compositions, articles, devices, and / or methods claimed herein are made and evaluated and are intended to be purely exemplary and are not intended to limit the disclosure. Efforts have been made to ensure accuracy with respect to numbers (e.g., amounts, temperature, etc.), but some errors and deviations should be accounted for.EXAMPLE 1

[0089] UV radiation absorbing highly transparent and colorless or neutral color soda-lime-silica glass compositions are developed. In non-limiting examples shown herein, glass can contain cerium and iron oxides as UV-absorbing agents. It was unexpectedly found that iron (II) oxide can reduce transmission of UV radiation in soda-lime-silica glass, and cerium dioxide can improve visible light transmittance of iron-containing UV absorbing glass.

[0090] Without wishing to be bound by any theory, it was hypothesized that a mixture of iron (II), iron (III), cerium (III) and cerium (IV) oxides can produce synergistic UV absorbing effects and favorable visible light transmittance. Previously it was demonstrated that the addition of UV absorbing oxides can impart undesirable color tints to the glass body, and therefore decolorization of such glasses may require high levels of physical and chemical decolourisers and which may subsequently reduce visible light transmittance and clarity of glass products.The inventors have unexpectedly discovered that the addition of zinc oxide can neutralize yellowish and greenish tints caused by cerium and iron oxides by shifting chromatic values of a* and b* to more neutral values, and therefore can bleachvisible color in UV radiation absorbing glass. It was found that even small amounts of physical or chemical decolorizers added to the glass can allow for obtaining more neutral-colored and highly transparent UV-absorbing glass compositions.

[0091] The glasses disclosed in this example are modified soda-lime-silica glass compositions, which can be used in the production of tableware and container glass. Glass compositions for producing low ultraviolet radiation (UV) transmitting articles may exhibit a neutral color or if desired, lightly tinted and high visible light transmission glasses.

[0092] Traditional flint (colorless) container glass transmits a significant portion of UV radiation; therefore, foodstuffs contained in flint container glasses are directly exposed to the harmful effects of UV radiation. Ultraviolet radiation degrades vitamins, proteins and lipids in foods, and the generated photo-degradation products can lead to discoloration, undesired odor, as well as loss of aroma, taste and essential nutrients in foodstuffs. Therefore green and amber glass containers are preferred to reduce or completely prevent the UV radiation-induced degradation of foodstuffs; however, colored glass containers mask the content of the containers, and therefore they may not be desirable for users. Furthermore, it is known that melting, refining and conditioning of such colored glass melts tend to be more difficult than working with flint glass melts. It is, therefore, soda-lime-silicate glass compositions that absorb significant portions of ultraviolet radiation that have been disclosed in this invention.

[0093] This non-limiting example presents a fairly neutral or tinted glass; for a thickness ( / ) of ~5.2 mm, having a visible light transmission (i.e. , Tv> 80) between (and including) 380 and 780 nm and a low transmission of UV radiation (i.e., Tuv< 45) between 300 and 380 nm (and including). Based on spectral calculations, iron redox of example glasses (weight %. ferrous iron I total iron) concentration is less than 50% for cerium, iron and zinc oxide-containing glasses. Glasses in this disclosure include cerium dioxide, di-iron trioxide, zinc oxide and preferably cobalt oxide and selenium. Cerium oxide can be in a range of 0.09-1.00 wt. % (more preferably less than 1.0 wt%, and most preferably less than 0.5 wt. %), di-iron trioxide a range of from 0.01-0.25 wt.% and more preferably a range of 0.125 and0.25 wt.%, here total iron oxide is expressed as the sum of ferric and ferrous in a glass matrix. Cobalt oxide and selenium can be used to decolorize or compensate for the yellowish tint of the glass, and the amount of cobalt oxide and selenium can range from 0 to 0.02% each, depending on the iron redox as well as the amount of optical absorbents (particularly cerium dioxide and di-iron trioxide) present in the glass. Table 1 shows a summary of an exemplary glass composition used in the current disclosure.

[0094] It was unexpectedly found that cerium dioxide coupled with di-iron trioxide can provide more cost-efficient UV absorbance in certain aspects of this disclosure. Cerium and iron oxides as UV absorbents also impart yellow coloration in the glass, and the yellow color can be decolorized more effectively than the green coloration in the glass. Further to this, the addition of zinc oxide bleaches the yellow coloration caused by the addition of cerium and iron (III) oxides substantially and shifts chromatic values of b* to more neutral values (a positive and negative sign of b* represent a yellow and blue component of the color, respectively); and more interestingly and unexpectedly zinc oxide removes the greenish tint caused by a combination of iron (II) and iron (III) oxides or impurities such as chromium oxide, and moves chromatic values of a* to more neutral values using the L*-a*-b* color coordinate system.

[0096] The definition of soda-lime-silica glass here is in its widest sense, and it relates to any glass compositions which can comprise the following oxides - but not limited to them - within their specified compositional range (concentrations are defined by weight percentage, Table 2):

[0097] Table 2. Example Soda-Lime-Silica Glass compositionSiO265-75 %Na2O 8-20 %CaO 0-15 %MgO 0-10 %AI2O30-5 %B2O30-3 %K2O 0-3 %Li2O 0-1 %SO30.0-0.50%

[0098] In this example, silicate glass contains SiO2, which is the main network former in glass, and therefore total SiO2content should be in a range of 65-75 wt.%. Otherwise, silica contents lower than the proposed range can deteriorate the chemical durability and crystallization properties of glass, and SiO2contents higher than the specified range can deteriorate the melting, refining and crystallization properties of the glass melt. It should be noted that crystallization properties in this patent refer to mainly liquidus temperature and the rate of crystal growth, and the extent of variation of these crystallization properties can also be linked to the crystal phase field of glass.

[0099] Na2O is the main network modifier or fluxing agent in the glass, and it should be in a range of 8 - 20 wt%, and the concentrations of Na2O lower than the proposed range can deteriorate the meltability and crystallization properties of glass melt. Na2O concentrations higher than the given range impair chemical durability, thermal shock resistance and forming properties of glass melt.

[0100] K2O can also be added to glass as a network modifier or fluxing agent. Addition of K2O is not essential, but the coexistence of K2O with Na2O can improve the mechanical properties and chemical durability of the glass due to the mixed- alkali effect. However, the amounts of K2O should be restricted to up to and including 3 wt% as it is an expensive fluxing agent, and its excessive incorporation in the glass matrix can reduce the hydrolytic resistance of the final glass product.

[0101] l_i2O can also be added to glass as a network modifier or fluxing agent. Addition of U2O is not essential, but the addition of small amounts of U2O can reduce the melting and refining temperature / time of the glass melt. However, U2O is a very expensive component, and excessive additions may deteriorate the crystallization properties of glass melts. Therefore U2O can be in a range of 0-1.0 wt% in the glass.

[0102] B2O3 can also be added to glass as a network former or fluxing agent. Addition of B2O3 is not essential, but the addition of B2O3 can significantly improve the meltability of soda-lime-silica glass; however, B2O3 is a relatively expensive component, and excessive additions may increase Na2<D volatilization from glass melts; therefore B2O3 can range from 0 to 3.0 wt.% in the glass.

[0103] AI2O3 can be added as a network former in glass to improve particularly crystallization properties of melts and mechanical properties of the final glass. The presence of AI2O3 is desired but not essential; however, excessive additions of AI2O3 can deteriorate melting, refining, crystallization and forming properties of glass melt. Therefore the range of AI2O3 can be in the range of 0.0 - 5.0 wt% in the final glass.

[0104] CaO behaves as a network modifier in glass networks and can be used as a high temperature melting flux. The presence of CaO significantly improves the chemical resistance and mechanical properties (Elastic moduli and Vicker’s hardness) of sodium-silicate glasses, and CaO should be present in glass not greater than 15 wt% as it may significantly increase liquidus temperature and the rate of crystallization of soda-lime-silicate glass melts. Therefore CaO can be in a range of 0-15 wt.% in the glass.

[0105] MgO can be used in combination with CaO in soda-lime-silica glasses; partial replacement of CaO by MgO can lower density and reduce liquidus temperature of glass melts significantly and hence increases the temperature difference between gob forming and liquidus temperatures. The literature also reports that MgO reduces the rate of crystal growth in melts in near- or sub-liquidus temperature regions. MgO preferably can be present in glasses in a range of 0-10 wt.%; however, the more preferred level of MgO in the glass can be in a range of 0-7.0 wt% as excessive use of MgO, particularly above 7 wt % can deteriorate crystallization properties and can also increase melting temperature of glass melts.

[0106] SO3 facilitates fining of soda-lime-silica melts, and therefore it can be incorporated in glasses through the addition of sodium or barium sulfate, gypsum or other forms of SOs-bearing minerals or compounds to glass batches. Glass compositions that fall within the defined compositional range can be melted under oxidizing or reducing conditions in order to control fining of glass melts and to obtain desired final color specifications. It is not limited to, but preferably dissolved sulfur in the form of SO3 can be in a range of 0-0.5 wt.% in soda-lime-silica glass, depending on the desired processing parameters.

[0107] Cerium oxide can be found in Ce3+and Ce4+states in soda-lime-silica melts, and the addition of cerium dioxide significantly reduces the transmission of UV radiation in certain embodiments of the invention. However, this effect does not vary linearly with the concentration of cerium oxide (see Figure 1), and levels of 0.5 wt.% or can be in the range of 0.25 and 0.5 wt.% would be the optimum concentrations for cerium oxide to be used. Chromatic value of b* significantly shifts to more positive values due to the presence of cations of Fe3+and Ce4+in example glasses.

[0108] A mixture of ferrous and ferric oxides can exist in soda-lime-silica glasses as an impurity, or iron oxide can be incorporated deliberately into float I flat glass for controlling solar control properties. Iron redox can be adjusted by changing the batch redox number and furnace atmosphere. Ferric and ferrous oxides impart green-bluish and yellowish tints, respectively, in the soda-lime-silica glass. Ferric and ferrous oxides absorb the ultraviolet and infrared portions of the light spectrum, respectively.

[0109] Silica sand can contain titanium dioxide as an impurity and therefore trace amounts of titanium dioxide (for example, less than 0.1 wt. %) can be present in the soda-lime-silica glass. Titanium dioxide can exist in various coordination states in soda-lime-silica glass, depending on the melting conditions (redox), glass composition and interaction with other types of cations. For instance, Ti4+and Ti3+impart yellow and brownish / purplish tints in soda-lime-silica glass, respectively.Titanium dioxide can be added to glass to improve the absorption of UV radiation when further additions of cerium dioxide do not effectively reduce UV ray transmission.

[0110] Cobalt oxide and selenium can be added in order to decolorize unwanted tints in glass bodies, and cobalt oxide can be used to compensate for the yellowish tint caused by the addition of UV absorbents of iron (III) and cerium oxides. However, excessive use of cobalt oxide can reduce visible light transmittance of UV-absorbing glasses. Selenium can also be incorporated in the UV-absorbing glass matrix; however, selenium is very volatile and therefore achieving stable decolorization is difficult, and the addition of excessive selenium can also reduce visible light transmittance and brilliance of UV-absorbing glass. On the other hand, zinc oxide behaves similarly to cobalt oxide and selenium and shifts a* and b* values to more neutral parts of the L*-a*-b* diagram, and successfully removing undesired greenish and yellowish tint without compromising the visible light transmittance and brilliance of UV absorbing glass. On the grounds of cost, preferably, zinc oxide can be used in combination with relatively low levels of cobalt oxide and selenium to fully decolorize the UV-absorbing glass.

[0111] It should be noted that soda-lime-silica glass can contain any other oxides in the form of impurities including, but not limited to, NiO, Cr20s, Sb20s, P2O5, AS2O3, Er20s or MnC>2.

[0112] The oxides herein disclosed can be incorporated into the glass structure by any conventional method. For instance, the disclosed UV absorbents and / or decolorization agents can be incorporated into the glass by mixing with other raw materials and can be fed into a glass melting tank. Furthermore, UV absorbents and / or decolorization agents can also be fed to a preferred forehearth in the form of low melting glass, frit or agglomerates to achieve the desired glass composition, which can provide flexibility over coloring and adjusting the production capacity of the UV absorbing glass products.EXAMPLE 2

[0113] Raw materials are batched to obtain the benchmark and example glasses, whose chemical compositions are tabulated in Table 3-7. Glass batch is melted in a Pt crucible in an air medium for around 12 hours at temperatures in a range of 1425-1450 °C considering modeled melting temperature; afterward the glass melt is poured and fritted and re-melted for another 12 hours in air medium for compositional homogenization. In total, 24 hours of melting in ambient air are deemed to be sufficient for the redox equilibrium of optical absorbents in glass melts to be reached. The glass melt is then cast onto a stainless steel mold and annealed at its expected annealing temperature for one hour, and then cooled to room temperature. A small fraction of total Na2<D in the glass is provided from sodium sulfate, added to improve the refining of the glass.

[0114] Cast glass bars were cut and polished to form specimens of ~5.2 mm thickness. A Shimadzu 3600 - UV-Vis-nIR spectrophotometer was used to measure the UV-Vis-nIR spectra of the produced glass samples in the range 190- 2500 nm. Tuv denotes the calculated total transmission of ultraviolet radiation in a range of 300-380 nm, and Tuv values were calculated according to the procedure given in the ISO BS 9050 standard, and similarly, the overall light transmission (Tv) in a range of 380 and 780 nm was calculated according to the methodology given in ISO BS 9050. The colorimetric CIE values of L*, a* and b* were calculated using the D65 illuminant and 10° observer considering the CIE 1931 standards. Spectral iron redox was calculated using the correlation of Ceglia et al. (2015) for soda-lime- silica glass, as follows:

[0115] wherein CFez+ is the concentration of iron (II) ions in % wt. in glass, and AHOO is the normalized absorption of example glasses to a thickness of 1 mm.EXAMPLE 3

[0116] The composition of Ex. 1 , which is given in Table 3, represents the benchmark glass composition, and Ex. 2 is obtained by a single addition of 0.25 wt. % di-iron trioxide to Ex. 1 (base glass). This addition was found to reduce the ultraviolet transmission of the Benchmark glass as shown in Ex. 2 with iron redox (FeO / ZFeO+Fe2C>3) of 91.42 %, and this surprisingly demonstrates that Fe2+ions also significantly absorb UV radiation in soda-lime-silica glasses. Without wishing to be bound by any theory, it was suggested that some fraction of the total iron oxide should be found in the divalent state in UV radiation-absorbing glass matrices, and therefore redox values can be in a range of 10- 50 % might be preferred as ideal iron redox values for UV absorbing glasses. Similarly, an unexpected reduction in UV radiation transmission can be observed for 0.25 wt.% cerium oxide-containing glasses in Ex. 3. It was found, however, further additions of CeC>2 in Ex. 4 and 5 do not reduce UV transmission as is expected when considering the individual effect of cerium dioxide in Ex. 3 (See Figure 1). Furthermore, the addition of di-iron trioxide to cerium oxide containing glasses, as shown by Ex. 6 and 7, can further reduce the transmission of ultraviolet radiation to nearly equivalent to that of excess cerium dioxide levels above 0.25 wt.% (See Figure 3), and the iron redox of Ex. 7 decreases to the value of 31.5 % with the addition of 1wt. % cerium dioxide. Incorporation of di-iron trioxide slightly reduces visible light transmittance, as is observed in Ex. 2, whereas Ex. 6 and 7 demonstrate that incorporation of cerium dioxide can remarkably improve visible light transmittance of iron-containing glasses. Addition of 0.125 wt.% zinc oxide to the glass in Ex. 6 moves chromatic values of a* and b* to more neutral values, and the value of a* shifts from -0.93 to - 0.54 and the value of b* moves from 2.57 to 2.03 in Ex. 8. Moreover, the addition of 0.5 wt.% zinc oxide to the glass in Ex. 4 moves the value of a* from -0.63 to -0.26 and the value of b* from 1 .37 to 0.84 in Ex. 9 (See Figure 2).
