AMACO KI-11 Snow Drift – Kiln Ice Crackle Glaze (Brush-on), 472 ml

Snow Drift is a translucent, milky white glaze that creates a stunning "snowflake" crackle effect. After firing, a delicate network of hairline cracks (crazing) develops on the surface, giving your pieces a frosted, multi-layered visual texture. For the most dramatic crackle pattern, apply 3–4 heavy coats.

Key Features:

• Beautiful Crackle Effect: Creates a unique, iced appearance.
• Translucent white that works beautifully over colored slips or dark clay.
• Firing range: Cone 5 (1186°C).
• Note: Due to the intentional crazing (cracks), this glaze is not recommended for dinnerware as bacteria can grow in the cracks.

Recommended Firing Schedule (Cone 5–6 crackle fire, tested and confirmed working):

1. Ramp 50°C → 104°C at 83°C/h (approx. 39 min)
2. Ramp 104°C → 1082°C at 222°C/h (approx. 4 h 25 min)
3. Ramp 1082°C → 1199°C at 56°C/h (approx. 2 h 5 min) – briefly exceeds Cone 6
4. Drop 1199°C → 1149°C at the kiln's fastest rate, then hold 30 min – this step creates the crackle, don't skip it
5. Controlled cooling 1149°C → 500°C at 150°C/h (approx. 4 h 20 min)
6. Free cooling 500°C → room temperature, kiln closed (often overnight)

Total active program time: approx. 11 h 40 min. Apply over bisqueware fired to approx. 1060°C, in 3–4 heavy coats. Let pieces sit 1–2 days after firing for the full crackle effect to develop.
