Mixing Powdered Glazes:
- Always wear a mask when mixing powdered glaze.
- Gently add the glaze powder to water in a bucket, avoid adding all at once to prevent clumping.
- Mix glaze using either a hand or electric whisk for 10 minutes
- Sieve the liquid glaze using an 80 or 100 mesh sieve, working all the material through the sieve using a stiff brush.
- The glaze mix should have a creamy viscosity, remember it’s easier to thin a glaze so begin with a thicker mix than you expect.
- Although all our glazes are and non-toxic, it is essential in any pottery studio to minimise inhalation of silica dust. Always clean up with a damp sponge and if any dust is airborne, such as when mixing powder glazes.
Glazes that have a low clay content do tend to settle more quickly. We find that adding a small amount of calcium chloride liquid (one or two tablespoonfuls per gallon) is helpful. Do be careful however, not to overdo the calcium chloride as this can lead to a fault known as 'plucking' in which the glaze cracks and pulls away form the body during firing.

"I have struggled to get this to the blue as advertised in the picture. It comes out a very weak milky blue/beige, not very attractive! It also runs. But as already mentioned, may need to fire to a higher temperature."

"1.4SG 3 second dip cone 6 looks wonderful with blue crystals and light blue on cup rim. Bottom shelf slightly under fired and looks like a regular blue. So hotter is better. Wax resist was a mistake I think. Runs if thick. "
