Colour & firing notes

Mayco suggests four or more coats for a fully saturated opaque finish. At cone 10 reduction, rich brown undertones become more apparent.

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

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.
