Vitraglaze Stoneware Glaze: True Matt Set

It has been a popular request for more matt colours, so we have developed a themed set of matt glazes that showcase the range of colours that can be obtained.

Our true matt surface is smooth and silky to the touch and incorporates micro-bubbling, which gives them their matt appearance. This contrasts with the underfired glazes sold as matt, which have a rough surface, hence the name true matt.

The set includes:

Dolphin Grey

Obsidian Blue

Olive Green

Sapphire Blue

Smoky Mint

White

These glazes are available until the end of December 2025. The most popular colour will become part of our permanent range.

Order before the promotion ends to avoid disappointment.

1222°C to 1280°C (Cone 6 to Cone 9).

The sample shows two applications on Vitraclay White Throwing Clay, fired to 1240°C.

The colourants used in this series include cobalt carbonate, copper carbonate, nickel oxide, and rutile; therefore, we advise that the coloured matts are not suitable for food-bearing surfaces. The white matt contains no colourant, but we have not tested it for resistance against acid. Please read our food safety advice.

If using the white matt as a base for your own colourants, please note that zinc can weaken colourants such as chrome and iron.

Experiment with the application thickness, as the two colours Smoky Mint and Obsidian Blue can easily turn black. The chemistry of this glaze has more zinc than boron, which can be beneficial if you desire fast firing.

If preparing from powder and applied too thickly, it will likely crawl on very absorbent surfaces. We suggest adding a little CMC to slow the drying process.

This glaze is unlikely to be safe for dinner/tableware. To be certain, you will need
to submit your wares for testing at a reputable laboratory. In the UK, the emphasis in law is to the ‘maker’ who takes responsibility for the food/dinner worthiness of a glazed or unglazed ceramic ware.
