Vitraglaze Raku Glaze: Royal Blue

A simple flat shiny blue, which will craze when taken from the kiln. Carbon will accentuate the fissures making distinctive black lines.

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.

• Be generous with the covering of the glaze
• Experiment with different combustible organic materials.

This glaze is unlikely to be safe for dinner/tableware. To be certain, you will need to submit your wares for testing at a reputable laboratory. In the UK, the emphasis in law is to the ‘maker’ who takes responsibility for the food/dinner safety of a glazed or unglazed ceramic ware.
