Description

[Technical field]

[0001] In this invention, a flat painting material such as a canvas or a three-dimensional object is used as a painting material, and a metal plate that is wettable with solder is attached as a component of the material. On the surface of the metal plate, or on the surface of the three-dimensional object covered with metal foil or metal powder, the solder is melted with a soldering iron while imagining the composition, and fine lines and uneven patterns are drawn, and then a picture is painted on the metal surface with a brush using a etchant as paint. How to create a pictorial sculpture relates to.

[0002] When a picture is drawn on the surface of a rough sketch made while the solder is melted, using one or more etchants, a unique color is created from the subtle color changes that occur due to the chemical reaction (mainly oxidation) of the etchant on the solder surface. By skillfully mastering the concentration and temperature of the etchant, as well as the gradation created by layering the paint, and the strength and weakness of the brush strokes, it is possible to create simple, delicate, and innovative expressions. How to create a pictorial sculpture The invention relates to the conventional technique using an etchant.

[0003] The history of stained glass began in France in the 12th century. Solder is an essential component in its production. The stained glass (attached photo 13) and glass objets d'art (attached photo 12) are made by wrapping tape-shaped copper foil (copper tape) with a width of about 5 mm and a thickness of about 0.03 mm around the cut surface of each piece of glass to create a picture frame, which is then welded and joined together with solder. The solder joints may seem like unnecessary parts, but they are a classic joining technique that remains unchanged even today, when glass adhesive joining technology has made great advances.

[0004] The solder coloring technique, which uses a corrosive liquid to color the thin solder frame black or brown to give the whole piece a chic, unified look, is known as an essential coloring method for stained glass production. However, this coloring technique using corrosion is merely painting and is not intended for painting.

[0005] The etching technique, which is a typical example of the intaglio technique (corrosion technique), which is one of the copperplate printing techniques, also uses a corrosive liquid, but the corrosion referred to here is a method of removing the part of the copper plate on which the image is to be drawn by corroding it with an organic acid such as ferric chloride solution, nitric acid solution, or citric acid solution, creating a depression, which is then filled with ink and printed by applying moderate pressure to the paper, which is a printing technique different from the present invention. There are also various geometric patterns created by photoetching, but these are also figures, How to create a pictorial sculpture isn't it.

[0006] Also, a coloring technique characterized by a vivid and calm blue-green color produced by an oxidation reaction with copper corroding solutions (ammonium salts, basic carbonates, etc.) is known as verdigris. It is a coloring technique that has been established as a technique for restoring bronze statues, busts, and their reliefs, as well as temple roofs, decorative Buddhist altar fittings, and Buddhist statues, and gives a sense of historical grandeur. However, these too How to create a pictorial sculpture isn't it.

[0007] In addition, finely ground malachite particles are used as a pigment to initially color copper ornaments and Buddhist statues, and over the years the color changes to a tasteful blue-green as natural corrosion progresses. This verdigris coloring is mainly a copper plate preservative technique that utilizes natural phenomena, and this coloring is also How to create a pictorial sculpture Pictorial Features of the Invention

[0008] One feature of this pictorial expression technique is that, like sumi-e landscape paintings, the basic colors are limited, but the technique differs greatly from conventional painting in that the artist paints while carefully determining the subtle colors that are produced by the chemical reaction between the solder and the etchant. The colors also vary subtly depending on the type and concentration of the etchant, the chemical changes that occur when the etchant is applied in layers, and the temperature and humidity of the atmosphere.

[0009] The changes in color tone create a sense of relief, light and dark, light and shadow, three-dimensionality, and perspective, and the use of masking tape and resist also allows the depiction of dots and lines to be emphasized. A soldering iron is used to melt solder and draw patterns according to the composition, and the tip is rounded or processed into a pick or spatula shape and used as a brush. By placing the soldering iron on top of a picture already drawn with etchant, remelting it to redraw the dots and lines, and then painting again with etchant, it is possible to create a more delicate expression.

[0010] For example, black patina, a commercially available etching liquid for stained glass, is suitable for expressing changes in light and dark like ink painting. Antique patina can be used in different ways to express color that gives the illusion of chance. Since the painting is expressed within a limited composition of solder-colored silver, a metal base, and a canvas, by emphasizing the positive (subject) and negative (background) of painting, and the contrast between light and dark, a chance factor is added to the calculated possibilities, and the unique charm and expansion of this technique can be expected.

[0011] By using a semi-etching liquid with a reducing effect at key points in the design, it is possible to add gradation to the color tone drawn with the initial etching liquid, or to create a composite expression that takes into account the background color of the solder and the background color of the underlying metal plate that constitutes the component material. On the other hand, delicate depictions of the brilliance of the stars, villages overlooked from a high mountain, and townscapes scattered in the distance can be depicted as more shining and unique expressions by sprinkling metal passivation particles such as gold and silver, chromium, and aluminum in the solder melted parts, as the metal particles will not oxidize in the etching liquid. In addition, the blank space of the canvas, such as the linen color, can also serve as a background color and be utilized as an element that highlights the pictorial expression technique of the present invention.

[0012] Furthermore, because the style of the two-dimensional works and the three-dimensional sculptures share a sense of unity, characterized by the same technique, combining and arranging these works as an installation (attached photo 11) can further expand the possibilities of pictorial expression. (Note) Semi-corrosive liquids with reducing properties refer to chemical substances such as hydrogen peroxide, hypochlorite, and hot water reducing sugar.

[0013] The metal plate or metal object that forms the base is a metal that is compatible with solder and has wettability, and is made of copper, zinc, tin, and other copper elements and their compounds, and of course these metal powders can also be used. Alloys containing gold or silver can also be used. It is also possible to melt the solder in an aluminum pot, cool it, and then make a thin plate of the solder, which can then be cut appropriately for use. Except for metals that form a passive state, such as aluminum, titanium, chromium, and molybdenum, thin plates of iron and stainless steel such as SUS304 can also be used.

[0014] When the three-dimensional object is made of clay or gypsum, or is made of stone or wood, it is convenient to cover it with copper foil or copper powder as the base metal. The thickness of the copper foil is 0.03 to 0.1 mm; the grain size of the copper powder particles is selected depending on the composition to be drawn, but it is usually in the range of 20 μm to 1000 μm.

[0015] The solder used in this invention will be explained below. Solder is an alloy, and solder with a tin to lead ratio of approximately 6:4 or 5:5 is widely used. Due to differences in metal diffusion coefficients, solder is divided into high melting point solder and low melting point solder, but either can be used. Tin-copper (Sn-Cu) and tin-silver (Sn-Ag) based lead-free solder, as well as tin-bismuth (Sn-Bi) based low melting point lead-free solder (melting point approximately 150 degrees) can be easily used if a soldering iron with temperature adjustment function is used. There are also solders that contain small amounts of gold, zinc, etc. depending on the application.

[0016] When different metals such as the heavy metal cadmium or gold are mixed, the melting point drops due to the phenomenon of melting point depression, and the mixing ratio of these metals has a significant impact on the color tone and texture when painting.

[0017] For solder melting equipment, if the underlying metal plate is thin, a normal soldering iron is used; for thick plates, a soldering iron with a large heat capacity to reduce thermal conduction loss, a propane gas torch, an acetylene gas burner for leaks, electric welding equipment, or other melting equipment such as ultrasound, lasers, or IH steel plate induction heating equipment is used to melt the solder and roughly draw the pattern; depending on the subject to be drawn, the tip of the soldering iron can be round or pointed like a pick, or a spatula-shaped copper iron which is suitable for drawing lines is preferred, as they have good thermal conductivity, are inexpensive, and are easy to work with.

[0018] When a soldering iron with a small heat capacity is used to melt solder on a metal substrate, the solder can be more easily melted if the metal substrate is heated in advance.

[0019] As solder flux, commercially available solder containing flux for machining is convenient, but fluxes based on ammonium chloride and zinc chloride gelled with purified water and natural fluxes such as rosin can also be used. By using these fluxes, it is possible to remove the oxide film on metals that are difficult to solder, increase wettability, and allow the solder to melt freely on the surface of the base metal. As an alternative method, it is possible to use solder by vapor-depositing the base metal using the vacuum deposition method without using flux.

[0020] Next, we will explain the solder etchant used in the present invention. Solder etchant is a traditional coloring technique that uses the color of the solder surface that develops through a chemical reaction (mainly an oxidation reaction) with the etchant, with a base color of brown or black. It is an antique patina that is indispensable for stained glass production, and is a compound whose main components are chemical agents such as nitric acid, sulfuric acid, dilute sulfuric acid, and hydrochloric acid, which has a weak oxidizing power. On the other hand, although there is of course a selection of catalysts and oxidizing agents, if chemical agents such as hydroxides of alkali metals or alkaline earth metals, ammonium salts, and ammonium carbonate are used as the etchant, not only the solder but also the copper or iron base metals can be colored white, blue-green, or reddish brown rust through a chemical reaction and used.

[0021] And, although it is not available commercially, a yellow similar to pale gold can be expressed by coloring with a corrosive solution in which gold leaf has been dissolved. In order to produce complex hues, the color gradation that occurs due to differences in reaction speed (depending on the concentration and temperature of the corrosive solution) is skillfully utilized even for similar colors, and the likelihood of the texture changing due to this subtlety is taken into consideration, and the concentration and temperature of the base metal (ground) and corrosive solution as well as the temperature and humidity control of the production space and the temperature of the cleaning solution used to wash away the corrosive solution and flux must be taken into consideration, and great care must be taken to prevent rust from peeling off due to water flow. After corrosion, the surface of the work must be treated to prevent discoloration from secondary oxidation due to air by applying oil to prevent oxidation, clear acrylic spray or acrylic varnish.

[0022] The solder etchant used in the examples of the present invention was drawn using commercially available solder etchants for stained glass, such as black patina, antique patina, and brown patina, taking into consideration the scientific nature and reproducibility of the invention. The white background was drawn mainly using plaster paint, but if a commercially available etchant, such as black patina with black rust color, is overpainted with a brush using an alkali or alkaline earth metal hydroxide and an oxidizing agent, hydrogen peroxide water, and then corroded again by the chemical reaction, the same white background as plaster can be developed. Furthermore, if an alkali metal hydroxide is reacted with solder, the surface turns white due to the composition characteristics of the solder, so it can be used to represent remaining snow, snowscapes, white clouds, and cloudy skies even without plaster paint. Modes of the present invention

[0023] The purpose of this invention is to form a base by attaching a thin metal plate to the surface of a painting material that will become a canvas, and to melt solder on the surface of the metal plate that forms the base with a solder melting machine such as a soldering iron while roughly drawing a pattern with the thin film, or to attach a solder plate to the surface of the painting material and melt its surface to draw a composition, and to paint a picture on the solder surface by using a solder etching liquid as paint and the color tone and gradation of the rust (oxide film) that occurs by the chemical reaction between the etching liquid and the solder. How to create a pictorial sculpture The purpose of this invention is to provide

[0024] The present invention is How to create a pictorial sculptureIn order to create this, the base metal (ground) that forms the component of the painting material that will become the canvas needs to be made of a material other than a solder plate, and it needs to be made of a metal that has wettability with solder.

[0025] Furthermore, when the canvas is a three-dimensional object, the object is a mineral or metal object that is wettable with solder, or a natural object such as stone or wood, or a processed object made from plaster or clay, and the three-dimensional object is coated with a metal foil or powder that is wettable with solder, and a picture is painted on the object using a solder etching liquid. How to create a pictorial sculpture The present invention provides the following examples: Example 1 Title of the painting: Mountain with remaining snow (attached photo 1) 1. Apply 0.06mm thick copper foil tape to the entire surface of a canvas of size F0 (180 x 140mm). Rub and press the tape against the canvas to ensure that no air gets in between the canvas and the copper foil tape. 2. Apply stained glass flux H (made by Taitori) evenly to the copper foil with a brush, and use a soldering tool (tip 5mm wide) to apply one bar of solder (approximately 25g x 3mm, melting point 183℃). Approximately one strip is used for each canvas area, and the composition of the painting is considered while creating accents and grooves, and then the paint is melted over the entire surface to create texture. 3. After applying the solder, thoroughly wash off the solder flux using a brass brush and household liquid detergent.

[0026] "The process of drawing a mountain" Next, Antique Patina (a stained glass etchant) is applied to the entire surface with a watercolor brush to cause corrosion, and masking tape is applied over the corroded solder along the lines of the mountains that have been designed previously on a separate piece of paper to protect the areas that will not be painted.Then, the entire area around the edges of the mountains is colored black with Black Patina EX (a stained glass etchant) (made by Garasu Land), and the painting is completed while creating colors that will create a gradation with the corroded colors of Antique Patina.

[0027] The masking tape is removed and the etchant is washed away with water to stop the progression of corrosion. White plaster paint is applied to the negative parts of the mountain background to create a contrast between the mountain and the background. Before the etchant dries, a thin layer of acrylic paint matte coating material (Holbein Industrial) Gel Medium Matte / Acrylic Matte Medium is applied with a brush, which causes the etchant to turn white through a chemical reaction, making it look like there is still snow on the mountain. To finish, a coating of corrosion protection oil is applied to give it a glossy finish and the piece is complete. Example 2 Title of the painting: Sea of ​​clouds mountain (attached photo 2) 1. Apply 0.06mm thick copper foil tape to the entire surface of a canvas size F5 (352 x 273mm). Rub and press the canvas to prevent air from entering the canvas and ensure that the canvas and copper foil tape are tightly attached so that they do not peel off. 2. Apply stained glass flux H (Tytori Co., Ltd.) evenly to the copper foil with a brush, then use a soldering iron (5mm tip) to melt one stick of stained glass solder (25g x 3mmφ, 183℃ melting point) (about two sticks, or 63g, for the area of ​​the canvas) over the entire surface, creating a sense of mountain-like texture while considering the composition of the painting and creating accents and recesses. To finish, wash off the flux with a brass brush and detergent.

[0028] "The process of drawing a mountain" Using a sketch of the mountain as a reference, melt the solder and roughly draw the design, then use a watercolor brush to draw the mountain ridge with black patina, and then fill in the mountain shadow with black patina. Before the black patina dries, paint the entire mountain with brown stained glass patina color (made by Tightly Co., Ltd.) so that the black and brown of the black patina create a gradation. Paint the sky that will form the background of the mountain with antique patina.

[0029] To stop the corrosion from progressing, rinse off the etchant with water and gently wipe off the moisture with kitchen paper. To fine-tune the color, apply the etchant to a cotton swab and rub it slightly to change the color and shape it into the mountain shape you drew. Since commercially available etchant cannot produce a white color, use plaster paint instead, randomly painting the sky with a brush so that some of the color of the corrosion remains, and also apply plaster to the sea of ​​clouds on the mountain, wiping off any excess plaster with tissue paper to make adjustments. Once the plaster has dried naturally, it is complete. Example 3 Picture title: Dead leaves 1 (attached photo 3) 1. Stick 0.06mm thick copper foil tape on the entire surface of an F0 (180x140mm) canvas. Rub and press the canvas to prevent air from getting into it, and make sure the canvas and copper foil tape are tightly attached so that they do not peel off. 2. Apply stained-glass flux H evenly with a brush to the copper foil that has been applied to the entire surface of the canvas, and then use a soldering iron (tip 5 mm wide) to melt a thin layer of stained-glass solder (25 g x 3 mm diameter, melting point 183°C), about one stick per canvas area, and spread it out while thinking about the design you want.

[0030] To create a difference in the texture of the leaves on the left and right sides, use a soldering iron with a 1mm tip to randomly apply 15g of solder from the center of the leaf to the left leaf, following the veins. On the right side, leave the solder flat and melted. Place a paper template in the shape of a leaf on the part of the leaf you want to color, and stick it to the entire canvas with masking tape from above. Use a cutter to cut the masking tape along the paper template and remove the paper template. Example 4 Picture title: Dead leaves 2 (attached photo 4) Use a watercolor brush to apply the etchant Antique Patina (sold by Garasu Land) to about two-thirds of the top surface, and before this dries apply Black Patina EX to the remaining third so that the boundary between the two etchants creates a gradation. To stop the corrosion from progressing, rinse the surface with water and gently wipe off the moisture with kitchen paper, taking care not to let the corroded parts fall off.

[0031] In Example 3, the solder is melted flat and then applied with random bumps and grooves toward the right side and in the direction of the veins, so that the color of the etching liquid due to the antique patina on the left side can be seen. Example 5 Picture title: Dead leaves 3 (attached photo 5)

[0032] Use a watercolor brush to paint the areas where you want to add leaf veins with flux, then use a soldering iron with a 1mm tip to remelt the corroded solder and bring out the base color of the solder to draw the veins. Wipe off with an alcohol-based cleaning solution (product name: Matsumura Metal Glass Cleaning Solution), paint antique patina with a brush, and paint black patina on the two-thirds of the leaf color that is close to brown, as well as on the parts where the solder base color is exposed. Paint the remaining one-third of the leaf color that was painted with black patina with a corrosive solution (made by Taitori) Patina Color Copper Color to create a contrast between the colors. Rinse with water to stop corrosion, and gently wipe off the moisture with kitchen paper. Example 6 Picture title: Dead leaves 4 (attached photo 6) The masking tape that had been stuck to the entire canvas is removed, and white plaster paint is applied with a brush, leaving behind the leaf image painted with corrosion. Plaster is applied in circular shapes in places to the leaf area to represent insect bites. After drying the plaster with a hair dryer, apply more plaster to any areas that need it, adjust the color, and let it dry naturally to complete the project. Example 7 3D sculpture Title: Rock (attached photo 7)

[0033] Prepare a moderately sized stone (weight 992g), brush off any dirt with detergent, wipe off the water with kitchen paper, and dry with a hair dryer. Tear copper foil tape (5.08cm wide, 0.06mm thick, with adhesive) by hand so that there are not many seams, and apply it to the entire stone, rubbing it to remove wrinkles and press down the stone to make sure the copper foil tape is tightly attached and to push out any air inside. For the area of ​​the stone, use about 2.5 rods of solder (73g) and spread it thinly so that the solder does not get in the way of filling in the natural unevenness of the stone. Once the solder has melted over the entire surface, use a brass brush and detergent to wash off the flux with lukewarm water of around 40°C, and gently wipe off the moisture with kitchen paper.

[0034] Apply black patina etchant to about one-quarter of the stone's ridge with a watercolor brush. Allow the etchant to drip onto the surface below, and before the etchant dries, apply antique patina to the remaining three-quarters of the stone's surface, creating a gradation between the antique patina and black patina.

[0035] The top of the stone is a monochromatic black patina, but the gradation of the antique patina brings out the beauty of the natural rock. To stop the corrosion, the etching solution is washed off with water and the moisture is gently wiped off with kitchen paper. Finally, after the patina treatment, a solder polishing oil is applied to prevent corrosion and the stone is completed. Example 8 3D sculpture Title: Lucky cat (attached photo 8)

[0036] Create a three-dimensional model of a maneki-neko (beckoning cat) using stone powder clay (Padico Stone Plasticine Lador 500g 303101). After 4 days of air drying, make small corrections using a cutter and sandpaper, then air dry for another 7 days. After drying is complete, apply water-based varnish (Padico Water-Based Varnish Sealer 303217) for waterproofing and to improve the adhesion of the copper foil tape, then dry.

[0037] Cut a 0.06mm thick copper foil tape into strips of appropriate size and paste it over the entire maneki-neko sculpture. Use a piece of cloth to push out the air and smooth out any wrinkles while simultaneously adhering the copper foil tape to the sculpture. Apply stained glass flux H (Tytori Corporation) evenly to the copper foil with a brush, then melt and spread the solder over the entire surface with a soldering iron (5mm wide tip) (approximately 25g per piece, 3mm diameter, melting point 183℃). After applying the solder, wash off the flux with a brass brush and detergent. Example 9 3D sculpture Title: Lucky cat (attached photo 9)

[0038] In the first step of coloring, apply masking tape to the solder parts that will not be coated with the etching solution. Example 10 3D sculpture Title: Lucky cat (attached photo 10)

[0039] With a watercolor brush, apply the etchant black patina to the model with masking tape attached, all over except the inside of the ears, and once you have confirmed that it has turned black, rinse off the excess etchant with water. Gently wipe off the water with kitchen paper to prevent the etchant color from peeling off, then remove the masking tape, apply black patina to a face brush, draw the pupils of the eyes, draw fine lines on the apron to create a striped pattern, and also draw a line around the mouth.

[0040] Apply brown patina color (Taitori Co., Ltd.) to a cotton swab and apply it to the inside of the ears and nose. Apply black patina diluted 8 times with water to the exposed solder base color with a cotton swab to lightly color it. Apply antique patina diluted 2 times with water to a cotton swab and apply it to the apron and other areas where you want to create subtle color changes. Rinse with water to prevent corrosion from progressing and gently wipe off the moisture with kitchen paper. Finally, wipe off any remaining solder polish flux with a rag and apply oil to complete the process. Example 11

[0041] Two-dimensional painting and three-dimensional sculpture Title: Lucky cat and mountain (attached photo 11) Combining the works from Examples 2 and 10, two-dimensional paintings and three-dimensional sculptures are spatially arranged to create an installation. Create a pictorial sculpture Effect of the invention

[0042] This invention is a pictorial technique of painting pictures on the solder surface using a solder etchant as paint. However, it is not limited to solder plates. A pattern can be drawn directly on thin plates such as copper, tin, zinc, and iron plates by hammering, pressing, etching, or other processing methods. Then, by melting and coating the surface of the processed base metal plate with solder, the unique texture and expression created by the flow of solder can be colored and painted with the solder etchant to create a novel pictorial relief, or on statues, bronze statues, and busts. How to create a pictorial sculpture If you apply and use it, you can create more realistic images. It will be a sculpture that can be expressed and created in a creative way and can be used industrially. .
