Note: Egg Yellow is a new underglaze formulated for those who want to fire to cone 6 or higher by applying multiple coats to produce an opaque colour. Thin applications produce excellent results too. When fired at cone 06, the colour is paler. Egg Yellow is based on a cadmium inclusion pigment (not recommended for use on food surfaces unless testing establishes that metals release is below legal limits.) and is most suitable for mixing with PSH Orange to produce intermediate colours.
PSH Underglazes are intense, intermixable, colours formulated for use from cone 06 to cone 10 oxidation. They are available in 50 mL, 250 mL and 500 mL sizes; select size from drop down/fly-out menu. The tall and narrow 50 mL size can be turned into a fine line pen by fitting the tip with small diameter steel nibs.
