Amaco Cosmos Glaze, color CO-05 Dark Matter

AMACO CO-05 Dark Matter, from the Cosmos Glazes (CO) series, is a crystalline/phase glaze for mid to high-fire applications.

Characteristics and Color Variation

This is a dark, fluid, and crystalline glaze.

• Cone 5: Produces large crystals with blue & violet highlights on a dark surface.
• Cone 6: The color transforms to a bright gold surface.

Application Techniques and Recommendations

• Application: Apply 4 coats on Cone 04 bisqueware.
• Ventilation within the piece: For best results, it is recommended to leave the inside or back areas of the piece unglazed.

Firing Schedule

• Can be fired using a normal medium-speed firing schedule without the need for a special cooling schedule.
• To achieve beautifully grown crystals and take them to the next level, it is recommended to use a controlled cooling schedule to accelerate crystal growth.

Caution Regarding Glaze Running: This glaze has a high tendency to run, so it is recommended to leave approximately 1/2 inch unglazed from the foot and to use a drip tray or soft refractory bricks under the kiln shelf to catch glaze drips.

Food Safety

• Although considered food safe according to standards after firing, it is not recommended for direct food contact surfaces due to concerns about surface durability.
