A sculptural glaze that puffs up magically in the kiln. Witchcraft! Shake well. Fire to cone 5/6. The more Magic Puff that is applied, the larger the puffs will become. Keep abundant space between ceramics in the kiln to allow space for the puff to expand. Magic Puff is very fragile and should only be used for sculpture. It is not food safe due to its fragility and texture. Firing Magic Puff multiple times increases strength and it becomes less brittle. Sold in Pints only.
