Who invented the paint for pictures of glass paintings?

The invention of paint specifically for glass paintings isn't attributed to a single individual, as glass painting has a long history that dates back to ancient times. Techniques and materials have evolved over centuries, with artists using various pigments and binders suited for glass. Notably, the development of stained glass in the Middle Ages involved creating specific glass paints that could withstand firing in a kiln. Today, modern glass paints are formulated for ease of use and durability, but they build on centuries of artistic tradition.
