Hi there,
I bought from SCARVA the BOTZ glazes - 9541, 9353, 9542 and 9342; and the Terra Colour glazes 5806, 5810, 5702, 5701, 5103, 5706, 5116, 5410, 5704 and 5115. I was looking for advice or guidance on the website to see if these glazes are safe for food / dinner ware e.g. bowls, dishes, cups, etc but I can't find the info. Can you advise whether the glazes I listed above are food safe please?
all the best
Jamie

If a glaze is food safe our 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 of glazes mentioned they are not ideal as usually the clay body itself would still not be vitrified meaning it would still be porous and often causing the glaze to craze as well. It is possible to do a high bisque and low glaze however it is difficult to apply the glaze to the bisqued pot as it is non porous. It is much easier to fire tableware to stoneware using glossy glazes and on a smooth body like our ES5 Earthstone Original, hope this helps.
