Overglaze pigments are paints used for overglaze painting. It melts at a much lower heat than the glaze to be painted, and although there are various types of overglaze paints with different properties and compositions, they are all composed of colorants and solvents. Colorants are mainly made of metal oxides, carbonates, or other salts, either singly or in combination, either raw or after appropriate heat treatment, and the solvent is a type of lead-containing glass.
