Colour & firing notes

Test on an upright form to assess the direction and extent of the streaking in your kiln.

How to apply

• Mix well before use and follow the jar instructions for the brushable formulation. Let the coating dry between coats.
• Use clay rated for cone 5–6. Test any layered combination separately, leaving enough space above the foot for the observed movement.

Food-contact suitability

Check the current jar label for food-contact suitability. A finished piece needs a sound, cleanable glaze surface that fits the clay and has matured correctly; a product label alone does not certify every clay, glaze or layered combination.

Before glazing a full piece

Fire a test tile on your chosen clay before glazing a full piece. Record the coats, firing cone and cooling programme. Photographs show example fired results; clay colour, kiln atmosphere and application can change the appearance.
