Abstract
In order to prepare particles of a vitreous enamel for use in forming a vitreous enamel body by fusing the particles together to form the body, at least one enamel frit and at least one non-vitreous additive are formed into an agglomerated granular feedstock and passed through a heating chamber whereby such feedstock becomes at least partially molten and rounded, whereafter the resulting rounded vitreous enamel beads are caused or allowed to cool to a temperature below their melting point.
