Frit

Frit is a type of finely ground ceramic material made from glass or clay that is heated until it melts and then cooled into small, porous pieces. In manufacturing, frit is used as an ingredient in glazes and coatings for ceramics and glass, helping to create smooth, durable surfaces. Because it melts at relatively low temperatures, frit improves the efficiency of the firing process and enhances the final appearance of the product. Think of it as a specialized, ready-to-use "ingredient" that improves how ceramic surfaces look and perform.
