• Underglaze
• Glaze Stain

Underglazes, glaze stains and body stains are a source of colour in decorating ceramic work, colouring glazes and slips or clay bodies.  We now refer to these products as colours or stains.  Some colours willl not work as a body stain although they will be successful as a underglaze or glaze stain (options are indicated at the top of this information).

When used as an underglaze he decoration can be applied to the greenware (dry clay) or bisque ware.  A transparent glaze if then applied over the pieces.  Invariably colour are not "strong" enough to burn through an opaque glaze. When used with opaque glazes colours are applied to the dry glaze surface.  This technique is known as "majolica" or "maiolica".

A coloured glaze can be easily produced by adding colour to a transparent glaze.  The amount of colour added will vary the strength and/or opacity of the glaze.  

Mixing Instructions:

For underglaze painting the colours should be prepared mixing 2 to 4 parts of colour to 1 part of Underglaze Flux (by volume).  Underglaze Media can then be added to produce a creamy consistency.  The finished mix can be cautiously diluted with water for application.

One common problem experienced with colours when used for underglaze painting is the covering glaze "crawling" back in the firing to leave the colour exposed or matt.  This is due to the colour not containing enought flux in the initial mix.  This problem can also be exaggerated if the colour is applied too thickly.  Adding flux will greatly reduce the risk of this occuring.  The amount of flux added will vary from colour to colour.

Tests should always be used to ensure the desired results will be achieved.
