Product Details

Product Information

Our very own Stoneware Glaze range, tested on all our Vitraclay bodies.

Available in liquid brush-on (ml) and powder (kg).

Firing and Working Notes

Firing Range:

1222°C to 1280°C (Cone 6 to Cone 9).

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

Suitable for Stoneware clay.

Working Notes:

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.

Health & Safety

Lead-free.

Refer to each SDS below for the individual hazards of each glaze.

General Advice:

When handled safely, a brush-on liquid glaze poses no risks, but avoid ingestion and contact with skin or eyes.

A powder or dried brush-on glaze presents a hazard as it may contain crystalline silica and other materials. When working with powders or when cleaning, wear an FFP3/P3 mask and filter and use a wet sponge.
