Bulk Powdered Raku Glaze with a Copper Matt Effect
Copper Matt Raku Glaze produces a metallic-effect surface whose colour and appearance can change through the Raku firing and reduction process. This variable response makes the glaze suitable for decorative ceramic pieces where an individual fired surface is preferred to a uniform result.
Choose the 25kg dry-powder format when a larger quantity is required for repeated mixing or a substantial body of work. Measure and record each batch carefully, then test the prepared glaze and application thickness before wider use because changes in mixing, firing and reduction can affect the outcome.
- Measure each batch consistently before making adjustments
- Keep records of the mixed consistency and application thickness
- Use test pieces to assess each batch before larger applications
