Blue stain in a low-fire porcelain: Creates the blue-white color of reduction-fired bodies

Thursday 27th October 2016

The top Zero3 porcelain bar has 0.07% Mason 6336 blue stain added (vs. none in the bottom bar). Zero3 is a frit-fluxed body, these SHAB test bars are fired at cone 03 in oxidation. To match the color of a insight-live.com/glossary/125">cone 10 reduction clear glazed Grolleg porcelain (e.g. L3778D) I add 0.05% stain blue stain (because the transparent glaze amplifies the color). In either case, to ensure that color develops, the body still must have adequate glass development (which is no problem in a fritware body).
