Studio Safety:

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 from the dried brush-on is airborne. wear an FFP3 mask.

Applying Brush on Glaze:

Remove glaze from pot, stir and agitate the glaze in a larger container, make sure all the material is mixed thoroughly. Whilst keeping the glaze moving, dip brush and hold sideways, in order to keep the material evenly distributed, then 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.
