Please can you advise as to whether this glaze has had a leach test undertaken on it? If not, whether it contains any toxic materials, such as barium, cobalt or copper. I was wanting to use this on domestic ware.

If a glaze is food safe or not depends on several factors including the type of clay used, the firing temperature, the shape of the vessel, the thickness of glaze even the position of the vessel in the kiln can have an effect on the glaze. Ideally a food safe test would be carried out by a reputable body like British Ceram. In the case the glaze mentioned it would most likely pass a food safe providing it was fired on a suitable body like our ES5 Earthstone Original in an electric kiln and to the suggested temperatures. Scarva can only advise on what products may be suitable but we are unable to guarantee if a product is food safe or not it is the responsibility of the customer to test and decide if materials are suitable for their required purpose. Hope this helps.

Terracolor Powder Stoneware Glazes are a more cost effective and faster approach to glazing a larger volume of pots. Simply mix the powder with water and pass through a sieve to create a dipping glaze. All Terracolor glazes are Lead Free.
