Powdered Raku Glaze for a White Crackle Effect
White Crackle Raku Glaze creates a white crackle-effect surface with a variable metallic appearance through the Raku firing process. It suits decorative ceramic pieces where the crackle response and natural differences between firings are intended to form a visible part of the finished design.
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 ratio, add extra water gradually where needed and test the glaze before important work because its colour and appearance can vary considerably between Raku firings.
- Mix thoroughly before adjusting the consistency
- Add any extra water in small, controlled stages
- Record the final mixture and application thickness for repeat tests
