I. Raw materials and tools
1, raw materials. Transparent flat glass or frosted glass, gouache pigment, traditional Chinese painting pigment, oil painting pigment, turpentine, varnish, thinner, etc.
2. tools. Painting pens (including all kinds of writing brushes and all kinds of oil painting pens and erasers); Coloring supplies (including water jugs, adjusting plates, color palettes, drawing paper, diamond glass cutter, fine sandstone, etc.). ).
Second, the production process
1, material selection. Choose flat and transparent glass or frosted glass without scratches and bubbles. If the frosted glass is processed with transparent flat glass, it can be treated with hydrofluoric acid, or polished with fine sand or emery above 120. When processing, attention should be paid to placing the glass smoothly and evenly, so as to avoid mottling or different shades on the glass surface. Cut glass with a diamond knife. Pay attention to the thickness of the glass, determine the thickness of the glass according to the size of the frame, and grasp the strength.
2. Draft. People who have basic knowledge of painting and are sure can paint directly on the glass. Ordinary people need to draw a draft on the drawing paper. When drawing a draft, we should consider that the work is viewed from the other side of the glass after completion, so we should be clear about the order of dynamics, left and right, people and animals. After the draft is designed, it should be pasted on the glass. In order to prevent mistakes, you can draw an outline on the back of the draft and then stick it on the glass. It's best to stick it under the baking lamp. 3. operation. When painting, you can hang the design on the workbench and paint while watching it. Operation method: 1. Detailed re-coloring method, after checking the line, re-coloring; The second method is intaglio coloring, that is, the background color is painted on the glass, and after the background color is dried, it is scratched on the background color with a needle or a knife to draw varied lines and faces, and then the lines and faces exposed from the glass are filled with colors as required to become intaglio works with layout style; Third, the gold and silver contrast method, after painting flowers and birds or figures on the glass, paint the background with gold powder or silver powder, so that the work presents a magnificent decorative effect; The fourth method is crayon painting, in which the glass is heated slowly and painted with colored crayons, and the wax can achieve special artistic effects after melting; The fifth is the multi-layer method. Taking advantage of the particularity of glass transparency, the far, middle and close views are made on two or three pieces of glass respectively, and then superimposed according to a factual distance to produce a sense of space visually. There are various methods of operation. Some are ink paintings, some are meticulous paintings, some are meticulous paintings, some are freehand paintings, some are oil paintings, some are prints, and some are calligraphy seal cutting. No matter what method is adopted, we should pay attention to the difference between the raw materials of glass painting and other paintings. It has a transparent, smooth and clean sense of material. This is the uniqueness of glass painting. When using gouache pigment or traditional Chinese painting pigment, you must choose the right one and mix the water evenly, because glass does not absorb water, and if there is too much water, it will soak into one piece. If you accidentally smear the wrong part, you can wipe it carefully with a wet cotton ball until it is clean.
4. painting. In order to preserve the picture for a long time, after some works are completed, a thin layer of varnish should be sprayed on the painting side, and attention should be paid to spraying it evenly to avoid the varnish flowing. If you brush varnish with a board brush, you should brush it in one direction, and you can't brush it back and forth repeatedly, so as not to stain the picture.
5, finishing. After the above process is completed, it can be installed on the frame and furniture according to the original design intention. The backing paper of glass painting is usually white. In order to achieve different effects, different colors of backing paper can be used.
