Vitraglaze is lead free and non-toxic.

Good housekeeping 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, wear an FFP3/P3 mask and filter.

Always wear a mask when mixing powdered glaze.

Dipping and pouring mixtures need to be tested on samples before being applied to final wares.

This method of application requires an understanding of the behaviour of liquid slurries on absorbent clay bodies, as results can vary for many reasons. Because of this, it is impossible for us to guarantee your wares will fire to the same colour advertised. Here is some useful further reading.

The glaze mix should have a single cream consistency. A useful tip is to use less water in the beginning as you can always add more. After mixing with water, use an 80 mesh sieve for stoneware and a 60 mesh sieve for earthenware.

For more about a dipping glaze, read our general advice.

Remove glaze from the pot, stir and agitate the glaze in a larger container, make sure all the material is mixed thoroughly.

Whilst keeping the glaze moving, dip your brush and hold it sideways to keep the material evenly distributed.

Apply using confident dabs, move the liquid around and work quickly and smoothly.

2 to 3 applications could be needed so allow to dry between coverings.
