Colour & firing notes

Choose it for decorative surfaces. Cone 10 reduction slightly flattens the texture without a significant colour change.

How to apply

• Stir thoroughly before brushing, especially when crystals or specks have settled. Follow the individual label for the coat count and let coats dry.
• The colour description uses the stated firing conditions. Cone 10 reduction can give a very different result from cone 6 oxidation; match the clay and kiln programme to the intended firing.

Food-contact suitability

Use for decorative surfaces rather than food-contact or drinking-rim areas. Texture or surface durability makes this a poor choice for those areas; choose a suitable liner glaze for functional ware.

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.
