Examples of this embodiment are for example known on the market under the trademark Ichendorf®. 15 Such a glass solution proved to be very inconvenient to use given the difficulty in cleaning the decorative element fixed to the bottom inside the glass. Another disadvantage is the possibility of breaking or ruining the embellishment element. during use of the glass, for example following the use of a teaspoon. It is also known from patent CN 111820690 a glass which comprises a portion 20 upper part made of glass and a lower portion made of ceramic, plastic or metal. In particular, the upper portion delimits two housing chambers of which the first housing chamber is open at the top and is suitable for receiving drinks and the second housing chamber is designed to receive an embellishment element. In more detail, after having fixed the embellishment element on the upper surface of the 25 lower portion using a sticker and having positioned the portion appropriately superior to the lower portion thanks to the engagement of an edge of the upper portion in recesses formed on the upper surface of the lower portion, the two portions they are rigidly connected by gluing so as to create an empty double bottom, corresponding to the second housing chamber, in which the aforementioned is placed 5 beautifying element. There are also several other solutions known for glasses that incorporate inside a chamber an embellishing element is created in the base of the glass itself. Some embodiments are described for example in US 740834, JP S6036776, US 2510237, US 6368531 and US 6036570. 10 Glass glasses with an embellishing element of the type known above incorporated into the base briefly described have proven to be not free from drawbacks. A first drawback lies in the fact that the processes for the production of such glasses keep visible the joint between the two parts of the glass that define the room with the embellishing element inside. 15 A second drawback lies in the fact that to date no tools have been developed processes that allow the production of a glass with a chamber integrated into it decorative element and which allow for a secure fixing of both parts of the glass which delimit the containment chamber of the embellishing element and of the element same embellisher on the bottom of the glass. 20 Presentation of the invention In this situation, the problem underlying the present invention is therefore that of to overcome the drawbacks of the known technique discussed above, by making available a glass and a process for its production, which allow for the incorporation of a decorative element separated from the volume of the glass intended to contain the 25 drink. A further object of the present invention is to provide a glass and a process for its creation, which allows to hide from view a functional junction section for separating a containment chamber containing the embellishing element, from the volume of the glass intended to receive a drink. 5 A further object of the present invention is to provide a process for producing a glass with an integrated beautifying element that is simple and reliable to make.

Detailed description of a preferred embodiment example With reference to the attached figures, an example has been indicated as a whole with 1 20 realization of glass cup with integrated embellishment element according to this invention, which is advantageously obtainable by means of a process, also subject of the present invention. The term "glass" should be understood as any object that can be used for contain liquid food items such as in particular goblets, cups, mugs, cups or even 25 carafes, bottles or similar. All the above mentioned products have in common that they are made of glass material in accordance with with the product and process described and claimed in this patent. In accordance with the example of the attached figure, the glass cup with embellishment element integrated according to the present invention comprises a concave containment body 10 5 in glass material equipped with a support base 11 delimited by a perimeter edge 13 and a perimeter wall 12 extending from the perimeter edge 13 of the base of support 11, up to its free perimeter edge 14. The support base 11 is equipped with an internal surface 11A, which participates in the definition of the concavity of the containment body, and of an external surface 11B. 10 The glass 1 therefore also comprises a glass body 20 made of glass material equipped with of a back wall 21 delimited by a peripheral edge and of a side wall 22 which extends from the peripheral edge 23 of the back wall 21 up to its mouth access 24. The back wall 21 is equipped with an internal face 21A arranged in the volume delimited by the glass body 20, and by an external face 21B opposite the internal face 15 21A. The containment body 10 is preferably cylindrical with the support base 11 of substantially circular shape. The glass body 20 has a cylindrical development defined starting from a bottom wall generator 21 which could be of any shape, although the circular one is still 20 once the preferential one. The glass 1 also comprises an embellishing element 100, which is fixed in correspondence of a second connecting portion 102 to a first portion of connection 15 of the internal surface 11A of the support base 11 of the body of containment 10. Without departing from the scope of protection of this patent, the following may be used: 25 planned plus embellishment elements 100 fixed to the support base 11 of the body of containment 11. The embellishing element 100 consists, for example, of a shaped body reproducing the appearance of an animal, a flower, a vehicle, a fruit, a tool, a boat, an airplane, a commonly used object or other ornamental figures. 5 Advantageously, each embellishing element 100 has a protruding appendage 101, which is intended to be fixed to the support base 11 of the body of containment 10, preferably in a centered position, as explained below. The fixing of the embellishing element 100 to the support base 11 of the body of containment 11 is obtained by softening a portion of the weld material 10 glassy which makes up the first or second connecting portion of the base of support 11 and / or of the embellishing element 100. Advantageously, the embellishing element 100 is also made of glass material even though it can also be made of another material such as metal. In the latter In this case, the fixing will be obtained by softening only the support base 11. 15 The embellishing element 100 is completely contained within the chamber of containment delimited by the containment body 20 and the bottom wall 21 of the body glass 20. The free perimeter edge 14 of the containment body 10 is contained inside of the area delimited by the back wall 21 of the glass body 20 and is fixed, 20 preferably centrally, on the external face 21B of the back wall 21 of the body glass 20 along a joint section 50 lying on the wall plane of the bottom 21 of the glass body 20 so that it is hidden from view by the thickness of the back wall 21 or also from the refraction of the back wall 21 of the body glass 20. 25 Preferably, the joint section 50 is arranged at an acute angle α defined between the perimeter wall 12 of the containment body 10 and an annular crown 210 of the back wall 21 of the glass body 20. This angle α is advantageously of 90 degrees and such annular ring is preferably circular. Advantageously, the step shape of the bottom of the glass thus created allows for 5 stack one glass inside another (i.e. with the containing body of a glass inserted into the mouth of the body of the glass of another glass) with consequent ease of transporting multiple stacked glasses and reducing space. The present invention also includes a process for making the aforementioned glass 1 with incorporated embellishment element 100, in particular according to the 10 features of the implementation example described above, the references of which will be maintained for ease of exposition. The above procedure includes a phase of preparation of a containment body 10 concave glass material comprising a support base 11 and a wall perimeter 12 extending from the perimeter edge 13 of the support base 11, 15 up to a free perimeter edge 14. The support base 11 is equipped with an internal surface 11A, which participates in the definition of the concavity of the containment body, and of an external surface 11B, which It is intended to act as a support once the glass 1 has been completely format wherever the user wishes to store it in its normal operating position. 20 The containment body 10 delimits a concavity with the aforementioned support bases 11 and perimeter wall 12 enclosing a containment chamber for an element 100 embellisher as described below. The term “glass material” refers to all silica-based glasses with any additions of other substances, for example "fluxing" substances such as borates and 25 melting point-lowering nitrates, i.e. lattice-forming oxides, oxides lattice modifiers, intermediate oxides, stabilizing substances that improve the chemical and mechanical properties of the glass produced, refining substances that facilitate the elimination of defects, colouring substances that alter the chromatic appearance of the glass product, bleaching substances that neutralize the color imparted by other substances, 5 opacifying substances for the production of opal glass. The process according to the invention therefore provides for a preparation phase of a plurality of embellishing elements 100 preferably also made of glassy material. Each embellishing element 100 consists, for example, of a shaped body reproducing the appearance of an animal, a flower, a vehicle, a fruit, a tool, a 10 boat, an airplane, a common object or other ornamental figures. Advantageously, each embellishing element 100 has a protruding appendage 101, which is intended to be fixed to the support base 11 of the body of containment 10, preferably in a centered position, as explained below. The embellishing element 100 is in any case contained after its fixing in the volume of the 15 containment chamber of the containment body 10 not protruding above the free perimeter edge 14 of perimeter wall 12. The containment body 10 is obtained with processes which are known in themselves and therefore not described. in detail as far as the technical expertise is concerned. Preferably, the The production process of the 10 glass container body uses the same technology as 20 production of glass glasses, which in particular involves for example the mixing of raw materials such as silica sand, sodium carbonate and calcium carbonate in proportions specifications. The mixture is then melted at high temperature in an oven usually around at 1500 degrees Celsius. The heat melts the mixture, bringing it to a liquid state. homogeneous molten glass. At this point, molding takes place by pouring the molten glass into 25 molds for the 10 glass container body, shaped according to the design desired. You can use one of several molding methods used in the production of glass cups for the production of the aforementioned containment body. Among such methods of Molding processes include, but are not limited to, blow molding and die molding. 5 The glass gradually cools inside the molds, solidifying and thus taking on the desired shape of the containment body 10. The mold is then removed and the containment body 10 is subjected to a process of controlled cooling avoiding internal tensions and ensuring resistance and durability of the glass containment body 10. 10 After cooling, the glass containment body 10 is subjected to machining processes finishing to eliminate any imperfections or burrs. A finishing process can be foreseen finishing aimed at including polishing the edges, removing marks. The embellishing elements 100, mentioned above, are also advantageously made of glass and can be made using entirely traditional molding methods. 15 Advantageously, the protruding appendage 101 is also one piece with the remaining part of the body of the embellishing element 100 also being made of glass material. The procedure therefore involves making available a glass body 20 at its vault defined by a back wall 21 and a side wall 22 which extends from from the peripheral edge 23 of the back wall 21 up to an access mouth 24 to the volume 20 containing the glass body 20. The back wall 21 is equipped with a face internal 21A, which represents the bottom of the glass on which drinks are poured, and a external face 21B, intended to be coupled in a fixing relationship with the edge free perimeter 14 of the containment body 10. The free perimeter edge 14 of the containment body 10 delimits an area contained in 25 that defined by the back wall 21 of the glass body 20, so that this edge free perimeter 14 can be completely supported along its entire development on the external surface 21B of the bottom wall 21 of the containment body 20. Advantageously this is done by maintaining an annular crown on the back wall21 external to the containment body 10. 5 Advantageously, the free perimeter edge 14 of the containment body 10 has a development circular. Advantageously, the bottom wall 21 of the glass body 20 has a circular development. The process of making glass 1 with integrated embellishment element 100 It therefore provides for a first phase of joining the embellishing element 100 on the surface 10 internal 11A of the containment body 10. Advantageously, this first phase of union It includes an initial warm-up phase (see figure 8 on the right) of at least one connecting portion 15 of the internal surface 11A of the support base 11 of the containment body 10 at a glass softening temperature, advantageously between 400 and 1,100° Celsius and preferably between 700 and 900°C, and 15 a compression step of a second connecting portion 102 of the element embellisher 100 against the first connecting portion 15 of the containment body 10 which has been softened following the first heating phase (see figure 9). This second connecting portion 102 of the embellishing element 100 corresponds advantageously at the free end of the protruding appendage 101 mentioned above. 20 This first heating phase is preferably obtained with a flame emitted by a C torch (or lance) producing a localized flame, for example that intercepts centrally the aforementioned internal surface 11A of the support base 11 of the body of containment 10. The heating lance or torch C is a tube-shaped tool tapered fueled by a combustible gas that ends with a nozzle that emits a 25 high temperature flame. Advantageously, before subjecting the first connecting portion 15 of the base of support 11 of the containment body 10 at the first heating phase in particular with the localized flame, an initial preheating phase of the entire body is foreseen containment 10 (see figure 7) by placing it for example above a source of 5 heat distributed or to a heating medium F1 (for example a stove or a body incandescent with radiant heating), to bring the containment body 10 at a temperature preferably between 180 and 300° Celsius and thus avoid the establishment of excessive localized tensions during the first warm-up phase which they could break the containment body10 itself. 10 Preferably, or otherwise as an alternative to the first phase of warming up the body containment 10, the embellishing element 100 advantageously made of material glassy is also or only it subjected to the first heating phase which it punctually concerns at least its second portion of connection 102 intended for mate with the first connecting portion 15 of the containment body 10 (see 15 figure 8 on the left). This first heating phase is also carried out, for example, with a torch or lance C' (advantageously a separate different lance employed in the first heating phase which heats the support base 10 of the containment body 10) also producing a localized flame that affects the second portion of connection 102 advantageously obtained with the free end of the appendix 20 protruding 101. Advantageously before compressing the second connecting portion 102 of the embellishing element 100 against the first connecting portion 15 of the base of support 11 of the containment body 10, both portions 15 and 102 are heated with the first heating phase (see figure 8). The different embodiments, i.e. 25 whether the first portion of the connection 15 is heated, or whether the second portion is heated of connection 102 whether they both heat up, they all provide that the first phase of heating results in the softening of a mass of glassy material by at least one connecting portion suitable for binding with the other portion to determine after cooling a strong mechanical fastening. 5 Advantageously, a second preheating phase of the entire element is provided embellisher 100 for example by placing it above a heat source or a medium heating F2 (see figure 6) to reach a temperature between advantageously between 180 and 300° Celsius and avoid the formation of localized tensions excessive during the subsequent processing phases which could break (or create 10 clicche) the same embellishing element 100. The first phase of joining the embellishing element 100 on the internal surface 11A of the support base 11 of the containment body 10, therefore has the purpose of carrying join together the softened glass material of the respective connecting portions 102 and 15 of the embellishing element 100 and of the containing body 10. 15 Preferably, the embellishing element 100 is, as anticipated above, equipped with a protruding appendage 101 which advantageously defines at its free end of the aforementioned second connecting portion 102, which is heated in this first heating phase to be fixed to the first connecting portion 15 of the containment body 10. In this way, the embellishing element 100 will be 20 supported on the support base 11 of the containment body 10 in a position raised with respect to its internal surface 11A thanks to the aforementioned appendix which acts from spacer. At this point, the intermediate semi-finished product 110 thus obtained is composed of the body of container 10 with the embellishing element 100 fixed on the internal surface 11A of the 25 its support base 11, is preferably subjected to a drilling phase of the its support base 11. This phase is obtained with a heated tip tool P (see figure 10), for example in metal material, which is pressed against the support base 11 of the containment body 10 until a through hole 200 is created. As will be clarified below, the aforementioned through hole 200 has the purpose of acting as a vent. 5 in a subsequent phase of the air production process which is generated in a chamber closed containment delimited by the containment body 10 and the back wall 21 of the glass body 20. At this point, a second phase of union takes place which includes a phase of juxtaposition (figures 13-16), in which the containment body 10 and the glass body 20 10 are brought closer to each other until they bring the free perimeter edge 14 of the body of containment 10 in contact with the external face 21B of the back wall 21 of the glass body 20 corresponding to their joint section 50. In accordance with the preferred embodiment of the present invention, the semi-finished product intermediate 110 thus obtained with the through hole 200 is then subjected to a phase of 15 mounting on a first spindle M1 (see figure 13) of a two-spindle M machine rotating opposite with the free perimeter edge 14 facing the opposite second M2 spindle. On the second spindle M2 of the same machine with two opposing rotating spindles M is then assemble the glass body 20 (see figure 14) with its mouth facing 20 the opposite first spindle M1 of the machine M. Advantageously, both the intermediate semi-finished product 110 and the glass body 20 are further subjected to a respective third and fourth preheating phase before be mounted on the respective opposite spindles M1, M2 (figure 6 in which however it is not illustrated the glass body 20) which brings them to a temperature between 25 advantageously between 180 and 300° Celsius. The approach phase is therefore preferably implemented by moving at least one spindle towards the other spindle so as to bring the semi-finished products into contact with each other intermediate 110 and the glass body 20 as specified above. Advantageously, once the two bodies 110 and 20 are made integral with the two opposite ones 5 spindles M1, M2, the latter move closer to each other, in particular by moving the spindle movable with respect to the fixed one up to a limit switch relative to a close position of the spindles (figure 16). With the spindles in this position at least one of the two is loosened spindles (M2 in the case of the example in the attached figures) the body associated with is repositioned this mandrel (i.e. the cup-shaped body 20 in the example of figure 16, 17) by placing it at 10 contact with the other body and the loosened spindle is closed to define the position of limit switch, the contact coupling of the two bodies. At this point, once the phase has been completed juxtaposition of the two bodies 10, 20 the operations of the second phase of union continue as specified below. This is followed by a rotation phase of the two bodies coupled with the containment body 10 15 resting against the glass body 20 in particular carried in this rotation by the two spindles M1 and M2 in phase with each other. This rotation phase occurs simultaneously with a second heating phase punctual of the joint section 50 by means of an elongated flame made by a elongated stem C2 which substantially covers the width of the glass (see figure 20 18). The joint section 50 runs parallel in front of the elongated flame. The free perimeter edge 14 of said containment body 10 is contained in the area delimited by the bottom wall 21 of the glass body 20 so that the phase of The approach foreseen here defines a step-like trend between the perimeter wall 12 of the containment body 10 and the bottom wall 21 of the glass body 20 with an interposed 25 acute angle α at the junction section 50. The joint section 50 is therefore located in the plane of the bottom wall 21 of the body glass 20 so that it is actually hidden from view which remains defined in correspondence of the acute angle a between the free edge 14 of the containment body 10 and the external face 21B of the back wall 21 of the glass body 20. 5 During the second heating phase the joint section 50 defines a plane on where the flame is placed, in particular of an elongated shape for at least the entire diameter of the joint section. Advantageously, the flame of the second heating phase is fixed being the torch advantageously mounted fixed on the M machine. In this way, the section of 10 joint 50 of the glass assembly 1 formed by the containment body 10 with fixed the embellishing element 100 and the glass body 20 fixed to the free perimeter edge 14 of the containment body 10, rotates in front of the flame to be subjected to the heating aimed at joining together the softened material of the free edge 14 of the body of containment 10 to the softened material of the external face 21B of the back wall 15 21 of the glass body 20. The high temperature of the flame causes the portions to soften against each other contact of the containment body 10 and the glass body with consequent interpenetration of glassy material which, once cooled, determines a fixing strong and distributed between the two components. Advantageously, at least one of the two bodies has 20 contact, and preferably both, will reach a temperature between 400 and 1,100° Celsius. When the softened glass materials interpenetrate at the the above mentioned joint section 50, the mechanical connection, once cooled down glassy material, it will be particularly solid. Being during the second phase of 25 rotating heating the assembly composed of the containment body 10 with fixed the embellishing element 100 and the glass body 100, the interpenetration welding of softened glass material will be extremely regular. This is precisely because of the rotation of the joint section 50 of the aforementioned bodies 10, 20 facing the flame; rotation that determines a uniform 360-degree continuity of the material 5 softened glass between the two coupled bodies. Furthermore, the joint section 50 is arranged at the acute angle α between the two bodies 10, 20, resulting completely hidden from view, appearing to the user to be determined by the simple refraction of the glass. During the above-mentioned second heating phase of the joint section 50 between the body of the containment 10 and the glass body 20, heating and expansion takes place 10 of the air contained in the containment chamber defined by the containment body 10 and from the back wall 21 of the glass body 20. The air inside this chamber expands and is evacuated from the through hole 200, previously made on the support base 11 of the containment body 10, and which acts as an air vent thus preventing breakage, deformation or cracking of the 15 same containment body 10. Preferably, before the phase of placing the containment body 10 together said intermediate semi-finished product 110 and the glass body 20, a fifth phase takes place preheating of the bottom wall 21 of the glass body 20 (see figure 17). This phase occurs preferably by rotating the glass body 20, advantageously 20 mounted on the respective spindle, with its bottom wall 21 placed close to the heating source such as a flame produced by a torch or lance heating mentioned above. This phase requires the back wall to reach a temperature preferably between 200 and 1,100° Celsius. Preferably, also the intermediate semi-finished product 110 with the containing body 10 25 fixed carrier the embellishing element is subjected to preheating preferably placing it on a heating medium F3 before the phase of approaching the body to glass 20 (see figure 11) for example at a softening temperature that relaxes internal tensions between 180 and 400° Celsius. Preferably, at the end of the second heating phase of the joint section 5 50, the containment body 10 after a cooling phase (even of short duration after the flame has gone out (see figure 19) it is released from the relative spindle (M2 in the case of the example) remaining supported by the glass body 20 integral with the other spindle. At this point and preferably the containment body 10 integral with the body a glass 20 (from its support base 11 to the joint section 50) is subjected to 10 a further third heating phase with a torch flame while the rotation of the glass assembly thus obtained (figure 20). This phase has the purpose of eliminate internal tensions that have been created in the previous phases and preferably involves bodies 10 and 20 reaching a temperature between 180 and 400° Celsius. 15 Preferably, at the end of this further third phase of warming up the body of containment 10 fixed to the glass body 20, the entire assembled glass assembly is subjected to a final phase of relaxation of internal tensions through a fourth phase heating at a lower temperature than that of the third heating stage placing it above a heat source F3 for a final time between 1 20 minutes and 30 minutes (see figure 11) at a temperature preferably between 180 and 300° Celsius. Finally, a final phase of occlusion of the through hole 200 is foreseen by inserting inside it of a hardening glue advantageously of the same chromatic character of the support base 11 of the containment body 10 and therefore for example transparent if 25 the containment body 10 is made of transparent glass.
