DEVELOPMENT OF ACID PROOF METALLIC LUSTER GLAZES IN MULTI COLOUR

Abstract

Various metals in small quantities, singly and in various combinations, were ground in ceramic frit. It was found that various colored lusters, transparent and opaque, could be developed under a fair degree of control of temperature from cones 010 to 1. After cooling to a dull red heat, the glazes were given a short reduction firing. Standard decorative processes were used with the luster glazes. Additional colors were produced by adding stains and metal oxides. Acid-resistant luster glazes were developed.
