Glass painting is an art form that involves applying paint to glass surfaces to create decorative images or designs. Artists often use special glass paints that are transparent or translucent, allowing light to pass through and enhance the colors. This technique can be used for various purposes, including creating stained glass windows, decorative panels, or even art pieces. The process typically begins with a design drawn on paper, which is then transferred to the glass. Artists may use brushes or other tools to apply the paint, and the finished piece is often baked to set the colors. Stained glass is a popular application of this technique, often seen in churches and historical buildings.
