Powdered Underglaze

Underglaze colours may be applied onto greenware or bisqueware using a suitable water based media (see 47051 Underglaze Media). Mixing of colour and media must be very thorough and is best achieved by working the colour into the media using a palette knife in a rubbing or lapping action. If sufficient flux is added, colours and stains can be made self-glazing and matt/satin colours developed. Powdered underglazes can also be used as glaze or body stains.

All powdered underglazes in this section are colour-stable to 1300C with the exception of 4530 Flesh Tint, 4531 Crimson, 4532 Purple Damson and 4550 Brick Red which are colour-stable to 1140C. Also, these four Chrome-Tin colours, plus 4542 Victoria Green, are not generally recommended to be used as slip or body stains due to unreliable colour response but should perform satisfactorily in a glaze.
