Abstract
In order to prepare particles of a vitreous enamel which is used to form a vitreous enamelled body by melting together the particles to form the body, an agglomerated granular charge is formed with at least one enamel frit and at least one non-vitreous additive and caused to pass through a heating chamber so that it becomes at least partly fused and rounded, after which the resulting rounded pearls of vitreous enamel are caused or allowed to cool to a temperature below their melting point. <IMAGE>
