Abstract
An overglaze decalcomania is provided which includes a prefused low melting point glass flux or frit as a protective layer and is substantially resistant to both acid and alkali attack, to mechanical abrasion, and inhibits release of lead, cadmium and other toxic substances normally found in decalcomanias. The frit is comprised of increments of lead oxide, silicon dioxide, cadmium oxide and tin oxide, and optionally titanium dioxide. It can include substituents of conventional frits as well. There is also provided a method for preparing such an overglaze decalcomania.
