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.
