Please Note

Please note that with the Terracolor Traditional range and the Staffordshire range the white glazes are made with chemical reactions and so, as with all non-stain glazes, the number of layers of glaze giving time for the reaction, and the temperature reached, and the heatwork can all create different effects from slight to significant differences.

SW Clear Glazes and Whites

This page lists the transparent, semi-transparent matt, transparent satin and white opaque stoneware glazes from a number of different ranges.

Glaze Mixing

We recommend sieving the powder before mixing to break it up, adding back any speckles for speckled glazes; we recommend using a powered hand mixer (drill with paddle spiral mixer or hand held blender for smaller lots) then sieve to ensure no agglomerated dry powder remains, and then rest it for two hours to allow any air to be absorbed and not create bubbles, pin holes when fired. For some glazes it is best to soak the powder with a little water first.

Dipping: Mix S/ware to double cream or slightly thinner to match the porosity of the bisque. Mix E/ware to single cream. Typical dipping recipe is E/ware 750/790gm liquid to 1000gm powder; S/ware 690/700gm liquid to 1000gm powder. Recommended liquid is 85% water to 15% medium or 2% SCMC cellulose solution. If you have problems keeping in suspension add 2% bentonite to the dry powder next time.  This is a starting point - you may need to add more liquid to get the consistency you like.

Brush On: Typical brush on recipe is 100gm powder to 40gm water and 50gm medium or 90gm of 2% SCMC Cellulose solution. For some dense glazes you may have to put in as much as 105gm of liquid.

If you have already mixed a quantity of glaze and it is falling out of suspension then you can use calcium chloride as a flocculent, particularly in E/ware glazes. Dissolve one flake in a small amount of hot water and then add to slop one drop at a time.

If you are looking for a velvety surface we recommend you use the satin glazes not the semi-transparent matts.

Please see advice at end of page regarding mixing of glaze powders into Dipping glazes and Brush On and advice on suspension and what liquid to use.

Make sure you wipe down the bisque ware to get rid of any salts.

Slow bisque firing can help prevent gasses being released later during glaze firing - these gasses can cause pin holes, peeling and splitting of the piece if not released during bisque firing.
