Powdered Raku Glaze for a Copper Blue Metallic Effect
Copper Blue Raku Glaze is a dry Milton Bridge glaze for creating a variable Copper Blue metallic-effect surface through Raku firing. It suits decorative ceramic work where changes in colour and surface appearance are intended to contribute to the individual finished result.
Choose the 1kg powder when you want to prepare the glaze for a selected application technique without moving to the larger 25kg quantity or the liquid brush-on format. Begin with the recommended mixing ratio, introduce any additional water gradually and test the glaze before important work because Raku results can vary considerably.
- Mix thoroughly before making consistency adjustments
- Record the final mixture and application thickness for comparison tests
- Treat reference results as guidance rather than an exact colour guarantee
