This borosilicate frit is high in calcium which means it will affect browns and iron oxide colors. This frit has a chemistry similar to an alumina addition to Frit 3134. It is intended for use in partially fritted glazes for wall tile and pottery, in lead bisilicate dinnerware glazes in the cone 3-5 range.
