Description

Technology Field

[0001] The present invention relates to stained Hanji and a method for manufacturing the same. Specifically, unlike Western stained glass which is completed using conventional glass, the invention relates to stained Hanji that captures the unique texture of Korean Hanji, as well as Korean sentiment, psychological stability, and philosophical feelings that emerge through the transmission of light, and a method for manufacturing the same. Background Technology

[0003] Generally, stained glass refers to window glass made by cutting or crushing colored glass or glass with a colored surface into geometric, decorative, or pictorial shapes, and then welding them with lead ribbons or joining them with various adhesives. It is mainly used for the decoration of windows in religious buildings such as cathedrals or churches, as well as large windows in medieval Gothic architecture, and for various interior items or indoor lighting.

[0004] These stained glass techniques have evolved based on the traditional leaded glass technique, which is most commonly used to attach pieces of colored glass containing metal oxides; copper foiled glass techniques that allow for the use of artificial lighting, such as in interior decoration or crafts; faceted glass or glass brick techniques that have developed in accordance with material changes in modern architecture; and glass brick techniques in which gemstones or thick glass are embedded in concrete.

[0005] However, techniques such as the lead mold, copper tape, and glass brick methods involve complex work processes that require a large workforce and, moreover, incur enormous production costs; consequently, they are installed only in extremely limited locations. Consequently, due to economic reasons, they are not being widely installed in numerous places where they are needed, such as small rural churches and other venues that lack financial resources.

[0006] Furthermore, while using glass can create a glamorous feel, there is a limitation in that it is difficult to express the clean, understated feel of an ink painting. Prior art literature

[0008] Korean Patent Publication No. 10-2022-0004410 The problem to be solved

[0009] The problem that the present invention aims to solve is to provide stained Hanji that can create three-dimensional expressions by using only light and Hanji paper, without directly coloring or drawing on the glass like Western stained glass, and a method for manufacturing the same.

[0011] The problems of the present invention are not limited to those mentioned above, and other unmentioned technical problems will be clearly understood by those skilled in the art from the description below. means of solving the problem

[0013] A method for manufacturing stained Hanji according to one embodiment for solving the above problem includes the steps of preparing a material, cutting Hanji to form a basic image, bonding Hanji to the basic image to form an image outline, and attaching Hanji to a point portion.

[0014] The above materials include Hanji, fermented paste, and lighting. The fermented paste can be obtained by obtaining a flour dough through the steps of mixing 5 kg of flour, 10 L of water, and 20 g of salt in a jar and aging it at a low temperature, and continuing the steps of removing impurities floating on the water, retaining the settled flour, and removing water once a day for 4 months, then drying the flour dough at 30°C to 50°C for 24 to 48 hours to make a flour stick, then mixing 300 to 500 parts by weight of water with 100 parts by weight of the flour stick, then heating it first at 90°C to 100°C for 15 minutes, heating it second at 70°C to 80°C for 10 minutes, and heating it third at 50°C to 60°C for 15 minutes, and then cooling it.

[0015] The step of forming a basic image by cutting the above Hanji may include the step of cutting the Hanji and the step of attaching the cut Hanji.

[0016] The step of forming an image outline by bonding Hanji to the above-mentioned basic image may include the step of expressing the image outline by continuously bonding Hanji onto the above-mentioned basic image while adjusting the amount.

[0017] It may further include a step for adjusting the strength of the Hanji outline.

[0018] The above Hanji is prepared by mixing wood pulp in a ratio of 35 to 45 parts by weight, Smilax china extract, and propolis extract in a ratio of 3 to 5 parts by weight to 100 parts by weight of mulberry fiber, and then drying it to a weight of 22 to 52 kg / cm² 2 It can be manufactured by calendering under pressure.

[0019] The above extract of *Tobokryeong* can be obtained by crushing *Tobokryeong*, extracting the crushed *Tobokryeong* with 25-55% alcohol at 40°C for 28 hours, and then concentrating under reduced pressure at a temperature of 65-85°C.

[0020] The above propolis extract can be obtained by mixing propolis and ethanol in a 1:5 ratio, then ultrasonically extracting at 55°C for 1 hour and 10 minutes using an ultrasonic extractor (sonication, JACOS), filtering the extracted 1:5 solution under reduced pressure, and concentrating the filtered filtrate under reduced pressure using a vacuum concentrator (rotor; buchi B-510) until the ethanol is completely evaporated.

[0021] Glycerin fatty acid ester and water can be added to the above-mentioned Tobokryeong extract in a ratio of 1:0.5 to 2:5 to 15 and mixed.

[0022] Stained Hanji according to another embodiment for solving the above problem can be manufactured by the method for manufacturing stained Hanji.

[0023] Specific details of other embodiments are included in the detailed description and drawings. Effects of the invention

[0025] Unlike Western stained glass made using conventional glass, stained Hanji according to one embodiment can provide the unique texture of Korean Hanji and the Korean sentiment, psychological stability, and philosophical feeling of light seeping through.

[0026] It is possible to use Hanji and light (natural light, LED light box) as a method of creating images and artistic expressions by allowing light to seep into Hanji, and to use them as works of art on the windows of cathedrals, churches, and modern buildings, while simultaneously producing them as modern art works (LED light box).

[0027] In addition, it can be combined with lighting to create lighting fixtures or various products, such as ceiling art for indoor spaces or the production of three-dimensional sculptures.

[0029] The effects according to the embodiments are not limited to those exemplified above, and a wider variety of effects are included in this specification. Brief explanation of the drawing

Specific details for implementing the invention

[0032] The advantages and features of the present invention and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below but may be implemented in various different forms. These embodiments are provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims.

[0033] This invention is an art technique that combines Hanji and light, and it is expected to become a turning point that opens new horizons for our unique Hanji art ahead of Hanji's planned inscription on the UNESCO World Heritage List in 2026.

[0034] Hanji is a general term for so-called traditional Korean paper made by using the paper mulberry tree as a raw material and piling it thickly using the sulluk method. It is paper produced using the bast fibers of the paper mulberry tree through the single-sheet papermaking method, a unique Korean papermaking technique. Recently, known as machine-made Hanji, it is mass-produced in rolls by mixing wood pulp or recycled materials with bast fibers or grass fibers, utilizing power machinery and chemicals for raw material processing, and adopting the same papermaking, pressing, and drying processes as Western paper manufacturing. Hanji produced using the bast fibers of the paper mulberry tree has the advantage of possessing high durability and preservation properties compared to general wood pulp, as its fiber length is longer (6.0–20.0 mm) and width is narrower, resulting in higher fiber strength. Furthermore, it contains a large amount of hemicellulose and flexible cells, which fill the gaps between fibers during the papermaking process and increase the bonding surface area.

[0035] While the West uses 'glass' and calls it 'stained glass,' the difference is that 'stained Hanji' does not directly use glass, and it is defined as 'Stained Hanji (Korean Paper).'

[0036] Specific embodiments will be described below with reference to the attached drawings.

[0037] FIGS. 1 to 3 are drawings referenced to explain the gradation of stained Hanji according to one embodiment, FIGS. 4 to 7 are drawings referenced to explain the manufacturing process of stained Hanji according to one embodiment, FIGS. 8 to 15 are drawings showing various embodiments of stained Hanji, FIGS. 16 to 17 are drawings showing the bonding glue of stained Hanji according to one embodiment, and FIG. 18 is a drawing showing the manufacturing process of stained Hanji according to one embodiment.

[0038] Referring to Fig. 1, when Hanji (HJ) of different or equal thickness is used to gradually increase thickness, differences in light and shadow are shown. For example, Hanji (HJ) may be in a form that extends in a second direction (Y-axis direction) that intersects the first direction (X-axis direction) and the first direction (Y-axis direction), and multiple Hanji (HJ) may overlap in the second direction (Z-axis direction).

[0039] More specifically, a plurality of Hanji (HJ) may include a first Hanji, a second Hanji, a third Hanji, and a fourth Hanji that are sequentially stacked in a third direction (Z-axis direction), and the first to fourth Hanji may be arranged to sequentially partially overlap in the opposite direction of the first direction (X-axis direction).

[0040] The first Hanji can partially overlap with the second to fourth Hanjis in the third direction (Z-axis direction).

[0041] The second Hanji partially overlaps with the third Hanji and the fourth Hanji in the third direction (Z-axis direction), and the second Hanji may partially overlap with the first Hanji in the opposite direction to the third direction (Z-axis direction).

[0042] The third Hanji partially overlaps with the fourth Hanji in the third direction (Z-axis direction), and the second Hanji may partially overlap with the first Hanji and the second Hanji in the opposite direction to the third direction (Z-axis direction).

[0043] The fourth Hanji can partially overlap with the first to third Hanjis in the opposite direction to the third direction (Z-axis direction).

[0044] In this way, if four or more sheets of Hanji are continuously partially overlapped and then illuminated, a darker tone effect can be obtained as the number of overlapped Hanji increases due to differences in transmittance. Additionally, when Hanji is cross-bonded, the light and shadow of the surface can appear monochromatic. Thus, a gradient effect can be produced by adjusting the light transmittance using the overlapping of Hanji. As Hanji of the same or different thicknesses are gradually overlapped, stepwise light and shadow (from white to black) are generated, and through such control of light and shadow, any image to be expressed can be created three-dimensionally.

[0045] Referring to Fig. 2, the edges of the Hanji (HJ) can be slightly bent and lifted to produce a gradient effect on one side. For example, when the Hanji (HJ) is bent in a third direction (Z-axis direction) and then illuminated, a gradient effect can be produced due to the difference in light transmittance from the light source in the bent area of ​​the Hanji (HJ).

[0046] Referring to Figure 3, four sheets of Hanji (HJ) can be sequentially partially overlapped in the opposite direction of the first direction (X-axis direction) and lifted while bending the edges to produce a stepwise three-dimensional light and shadow effect. More specifically, a plurality of Hanji (HJ) sheets may include a first Hanji, a second Hanji, a third Hanji, and a fourth Hanji that are sequentially stacked in the third direction (Z-axis direction), and the first to fourth Hanji sheets may be arranged to sequentially partially overlap in the opposite direction of the first direction (X-axis direction).

[0047] The first Hanji may partially overlap with the second to fourth Hanjis in the third direction (Z-axis direction), and the first direction (X-axis direction) end of the first Hanji may be rolled up in the third direction (Z-axis direction).

[0048] The second Hanji partially overlaps with the third Hanji and the fourth Hanji in the third direction (Z-axis direction), and the second Hanji may partially overlap with the first Hanji in the opposite direction of the third direction (Z-axis direction), and the end of the second Hanji in the first direction (X-axis direction) may be rolled up in the third direction (Z-axis direction).

[0049] The third Hanji partially overlaps with the fourth Hanji in the third direction (Z-axis direction), and the second Hanji may partially overlap with the first Hanji and the second Hanji in the opposite direction to the third direction (Z-axis direction), and the end of the third Hanji in the first direction (X-axis direction) may be rolled up in the third direction (Z-axis direction).

[0050] The fourth Hanji may partially overlap with the first to third Hanjis in the opposite direction to the third direction (Z-axis direction), and the end of the fourth Hanji in the first direction (X-axis direction) may be rolled up in the third direction (Z-axis direction).

[0051] At this time, if you continuously layer four or more sheets of Hanji and apply light, you can obtain an effect of increasingly darker tones.

[0052] In this way, as the Hanji is layered, the amount of light transmitted can be controlled to create light and shadow. Furthermore, if the edges of the Hanji are slightly lifted and bent in the third direction (the Z-axis direction), the contrast between surfaces becomes distinct, and a sense of three-dimensionality can be formed through a natural gradation (a phenomenon where light and shadow gradually become darker or lighter).

[0053] In one embodiment, four sheets of Hanji are overlapped as an example, but this is not limited thereto, and one sheet of Hanji may be used, or more than four sheets may be overlapped.

[0054] Referring to FIG. 18 together with FIG. 4 to 17, a method for manufacturing stained Hanji may include the steps of preparing materials (S10), cutting Hanji to form a basic image (S20), bonding Hanji to the basic image to form an image outline (S30), attaching Hanji to point parts (S40), and adjusting the strength of the Hanji outline (S5).

[0055] In one embodiment, the step (S10) of preparing materials may include Hanji, fermented paste, and lighting (including natural light). Here, the Hanji may include colored paper, and the thickness and size of the Hanji may vary. The characteristics of the Hanji used in the present invention will be examined in more detail later. In one embodiment, aged and filtered fermented paste may be used. However, it is not limited thereto, and various adhesive materials such as unfermented flour paste may be used.

[0056] Here, the process of preparing fermented paste may include a step of mixing 5 kg of flour, 10 L of water, and 20 g of salt in a prepared jar and aging it at a low temperature, and a step of skimming off impurities (proteins, carbohydrates) floating on the water, retaining the settled flour, and removing the water, continuing this process once a day for about 4 months. Through these steps, all impurities are removed and a strong flour dough can be obtained. Here, low temperature may refer to a temperature between 5°C and 12°C.

[0057] Afterwards, the flour dough can be dried at 30°C to 50°C for 24 to 48 hours to form a flour stick, and then, if necessary, 30g of the flour stick is diluted with 1L to 1.5L of water and heated for about 30 to 40 minutes (strong, medium, weak) to produce fermented paste. Specifically, 300 to 500 parts by weight of water are mixed with 100 parts by weight of the flour stick, then heated first at 90°C to 100°C for 15 minutes, then heated second at 70°C to 80°C for 10 minutes, then heated third at 50°C to 60°C for 15 minutes, and then cooled to obtain fermented paste.

[0058] When using such fermented paste, it becomes possible to firmly and harmoniously bond Hanji to Hanji, while simultaneously utilizing it as a semi-permanent preservation adhesive.

[0059] In one embodiment, the step (S20) of cutting Hanji to form a base image may include the step of cutting Hanji and the step of attaching the cut Hanji.

[0060] Referring to Fig. 4, the initial cutting and pasting of Hanji serves as the basic foundation for the light and shadow that forms the image. It is a method of displaying an image by controlling the amount of light entering from the outside through the overlapping of Hanji of different thicknesses. At this time, the Hanji is cut with a knife to create and paste the image.

[0061] In one embodiment, a frame for attaching Hanji may be prepared, and a background image (IM1) that fits the frame may be realized by cutting and attaching Hanji to the frame, and a base image (IM2) may be realized by additionally cutting and attaching Hanji to the background image. Such attachment work may be performed using the aforementioned glue.

[0062] In one embodiment, the step (S30) of forming an image contour by bonding Hanji to a base image can represent an image contour (IM3) by continuously bonding Hanji onto a base image (IM1) while adjusting the amount as shown in FIG. 5.

[0063] In one embodiment, the step (S40) of attaching Hanji to a point part involves attaching Hanji to a part that is primarily a point in the overall image to be created as in FIG. 6, thereby controlling the amount of light and revealing the point image (IN4).

[0064] In one embodiment, the step (S5) of adjusting the strength of the outline of the Hanji is to adjust the strength of the surface and the outline (IM5) of the Hanji as a finished Hanji stained work as shown in FIG. 7, and to adjust the gradient effect with lighting to give the final finished effect.

[0065] Referring to Fig. 8, the abstract representation technique of the image expresses gradual shading from light to darkness and combines with colored paper (CP) to produce a partially different effect. To achieve this method, the manufacturing method of stained Hanji may include an additional step of attaching colored paper (CP). The colored paper (CP) may be positioned anywhere among the multiple Hanjis. For example, the colored paper (CP) may be positioned at the very bottom, at the very top, or between the multiple Hanjis.

[0066] Referring to Fig. 9, the technique involves mixing light sky blue, red, and cream-colored Hanji to create a harmonious color gradation effect.

[0067] Referring to Fig. 10, the effect of a process in which vertical gradual shading and horizontal gradual expression are mixed is shown by utilizing the cream color of Hanji and colored paper.

[0068] Referring to Fig. 11, the Hanji is arranged diagonally and different light (warm light / cold light) is applied to the left and right sides, creating an effect where the light changes naturally.

[0069] Referring to Fig. 12, it shows that the relatively many step-by-step processes of Hanji have been simplified to show changes in light at the edges and a large image.

[0070] Referring to Fig. 13, the parts of the Hanji that are joined together and overlap significantly create a dark effect, showing an abstract image.

[0071] Referring to Fig. 14, Hanji paper was applied in stages to gradually create a sense of perspective, and partial colored paper was joined to allow another light to seep in, producing a three-dimensional effect.

[0072] The image on the right, which appears as a dark silhouette, uses a large amount of Hanji.

[0073] Referring to Fig. 15, light and shadow were created stepwise from white to black using Hanji.

[0074] In this way, as Hanji is layered, light and shadow can be controlled according to the thickness or amount of Hanji, and dark colors can be expressed by using thick Hanji to block light.

[0075] In addition, a characteristic feature of the present invention is that it creates a unique feel by forming a gradation (using glue) on each side of the Hanji.

[0076] Furthermore, to produce color, colored Hanji can be used or color dyeing can be applied separately to achieve the effect.

[0077] Additionally, you can create effects by coloring or drawing on Hanji.

[0078] Referring to Fig. 16, fermented paste that has been aged and filtered at low temperature for about 4 months is mixed with water and heated at high, medium, and low temperatures for about 30 minutes to produce a relatively thick paste. When heating, a wooden spatula is used to rotate the mixture in one direction while boiling.

[0079] Referring to Fig. 17, the finished paste is spread evenly using a wide brush to prevent clumping before use.

[0080] Hanji according to one embodiment is prepared by mixing 40 to 50 parts by weight of wood pulp and 3 to 5 parts by weight of *Tobokryeong* extract with respect to 100 parts by weight of *Dak* fiber, then drying and producing 20 to 50 kg / cm² 2 It can be manufactured by calendering under pressure. Since the extract of *Sophora japonica* has antibacterial properties, it can increase the preservation of Hanji, thereby effectively preventing the deterioration of Hanji. Such an extract of *Sophora japonica* can be obtained by crushing *Sophora japonica*, extracting the crushed *Sophora japonica* with 25–55% alcohol at 40°C for 28 hours, and then concentrating under reduced pressure at a temperature of 65–85°C.

[0081] In another embodiment, a glycerin fatty acid ester and water can be added to the Polygonum multiflorum extract in a ratio of 1:0.5 to 2:5 to 15 and mixed. The Polygonum multiflorum extract mixed with the glycerin fatty acid ester and water is heat-treated at a temperature of 50 to 100°C and cooled. When cooling, it is usually cooled at room temperature (18 to 25°C), and if rapid cooling is required, it can be rapidly cooled at a temperature of -20 to -40°C. The Polygonum multiflorum extract that has undergone such a cooling process can be used in the manufacture of Hanji.

[0082] In another embodiment, Hanji can be manufactured by mixing wood pulp in a ratio of 35 to 45 parts by weight, Tobokryeong extract in a ratio of 3 to 5 parts by weight, and propolis extract in a ratio of 3 to 4 parts by weight per 100 parts by weight of mulberry fiber, forming a paper, drying it, and then calendering it under a pressure of 22 to 52 kg / cm2. If propolis extract is further included, the preservation ability of Hanji can be further improved. Propolis extract can be obtained by mixing commercially available propolis and ethanol in a 1:5 (propolis:ethanol) ratio, ultrasonically extracting at 55°C for 1 hour and 10 minutes using an ultrasonic extractor (sonication, JACOS), filtering the extracted 1:5 (propolis:ethanol) solution under reduced pressure, and concentrating the filtered liquid under reduced pressure using a vacuum concentrator (rotor; buchi B-510) until the ethanol is completely evaporated.

[0083] However, it is not limited to this, and Hanji may also be made of 100% mulberry fiber.

[0084] Although embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will understand that the present invention may be implemented in other specific forms without changing the technical concept or essential features thereof. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive.
