Vitraglaze Raku Glaze: Copper Aqua

Use our Vitraclay Raku Clay or Sibelco White Hand Building Clay and bisque to 1000°C or 1100°C (Cone 06 to Cone 03).

Glaze fire 950°C to 1000°C (Cone 08 to Cone 06).

Samples shown on our Vitraclay raku fired bisque at 1000°C in an oxidising (electric) kiln. When the glaze was applied it was then reheated in an oxidising (electric) kiln to 950°C then transferred to a reduction environment.

The combustible organic materials used were woodchip and paper, and after it was quenched with water.

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. Glaze should be added to water according to the instructions. Mix the glaze for at least 10 minutes, sieve the liquid glaze using a 60 mesh screen, 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. 

See product attachment for mixing a dipping consistency in more detail.

The glaze mix should have a single cream consistency, remember it’s easier to thin a glaze so begin with a thicker mix than you expect.

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.
