Royal Blue Underglaze 50ml
This price is per 50ml, select multiples for larger quantities. Please bring a jar when collecting.
Underglaze can be applied on green or bisque fired ware and can be left unglazed or a clear glaze can be applied on top (the image shows the top section glazed and the bottom section unglazed), when work is fired to stoneware temperature it will vitfify and become non porous without glaze, however the underglazes can stain without a glaze.
If underglazes are applied to bisque ware it should be fired again to bisque temperature before the aplication of a clear glaze.
For a solid colour 2-3 heavy coats are required.
Will fire to Earthenware or Stoneware up to 1260.
