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 choose satin not matt - matt’s are semi-transparent and can be milky if thick or at lower temperatures. Matts are best for adding stains or oxides to if making a matt coloured glaze.

Please do wipe down bisque ware with a damp cloth to take away any salts that have come out of the clay during firing - especially with earthenware clays

Please see advice at the end of the page about mixing dipping glazes from powder.


Keep glaze firing problems to a minimum by bisque firing slowly so all the gasses come out then.
