Cone 6 oxidation (first image): Black Timber is a satin, opaque, mottled brown glaze that breaks over texture. Contains glossy brown crystals. Base colour is stable, crystals can create movement.  

Cone 10 reduction (second image): Colour becomes darker metallic, crystals flow more. Light application recommended.  

Tips:

• Upon opening, crystals will be concentrated in the bottom of the bottle. Stir/shake thoroughly to incorporate before each use.
• Crystals can create movement. Avoid having a heavy concentration of crystals near the bottom of your piece.
• When storing a crystal glaze, you may consider storing upside down to make crystal more accessible.
• Can be used in oxidation or reduction firings. Results may vary.
• The choice of clay body, thickness of glaze application, firing process and temperature will affect the fired results. Always test in your kiln, on your clay body
