GLAZE MIXING GUIDELINES

How much water to add to glaze powder?

I suggest to start with a ratio of 8:10 water to glaze. This depends on each glaze and how you plan to apply the glaze, but 8:10 is a good starting ratio.

Usually, from there, you need to add a bit more to get it around a SG (specific gravity) of 140-150. That means 100 ml of glaze will weigh between 140g and 150g.

Normally it ends up being 1:1 ratio, but better to start thicker and add more water later. If the glaze is too runny you can allow it to settle and discard the water from the top after a few hours.

I do suggest you make note of the SG (specific gravity) of each batch you make and record your glaze tests meticulously. Many special-effect glazes are VERY thickness sensitive so your success depends on it, as well as your ability to repeat your results.

For special effect glaze like lava or lichen the thickness can be made a LOT more thicker, like 5:10 (water:powder), especially if you are using them in brushing technique.

And if you find the glaze settles too much and is difficult to stir up- remember to add a deflocculant- some handmade glazes really benefit from this and become much more pleasant to deal with.

How much water to add exactly will depend on each glaze and how you plan to apply it and how thickly made/well absorbing your piece. Several glazes here can be applied with brush (so I suggest to make it more thick), others can be layered (means should be made more thinly) etc etc. That is why no specific water amount can be suggested- please do read application tips under each glaze.

Important - we make these glazes by hand, so powder is not mixed throughout, so you must mix the whole bag with water in one go to get even formula (YES, that means if you purchase the 5kg (11lb) bag it must mixed with water all at once to get the correct formula)!

(for 0.5kg powder you need 1 l bucket, for 5kg powder you need 10l bucket)

firing range

1240-1290 C (oxidation, electric firing) (orton cone 7 - cone 9)

(a few glazes (like the LAVA) just cone 7-8, not higher, please see specific recommendation under each listing)
