It is commonly used in the production of art glass, decorative glass, and other glass products with patterns or colors. Baking devices use high temperatures to create various patterns, colors, and effects on the glass surface. This process typically involves the use of paint, powder, or chemicals. The main principle of a baking device is to heat the glass surface, causing the paint to react with the glass surface to form a decorative pattern or effect.
