Glass painting is an art form that involves applying paint to glass surfaces to create decorative images or designs. Artists use special glass paints that can be transparent or opaque, allowing for a variety of effects. This technique is often used in creating stained glass windows, where light enhances the colors and patterns. The process typically begins with a design drawn on paper, which is then transferred to the glass. After painting, the glass is often fired in a kiln to set the paint, making it durable. Glass painting can be found in various applications, from religious artifacts to modern decorative pieces.
