Are all your porcelain glazes food safe?
|
Réponses de Scarva:

Hi,
Crackle glazes are not considered food safe becuase bacteria can develop within the cracks. If looking for glazes suitable for dinnerware you should look for gloss glazes and fire them on a suitable body to the recommended maturing temperature.
Hope this helps!

Can you use this on other stoneware clays or is it just for porcelain?
|
Réponses de Scarva:

This range of glazes works best on porcelain clay due to the whiteness of the clay body and the vibrancy it gives the fired glaze. You can use it on a stoneware clay however the colours will be much duller and muddy in appearance. Hope this helps.

Is this suitable for cone 5 to 6 firing?

Hi there, these glazes need to be fired to Cone 8/9.

Another new addition to the Scarva catalgoue is the beautiful range of Porcelain Crackle Glazes. These glazes were delveloped in the Scarva lab after ever increasing demand for crackle glazes especially for Porcelain bodies. They are available in both powder and brush-on and we recommend 2-3 coats. After firing the crackle should be given time to develop, usually around 48 hours is a good estimate. To further enhance the crackle, Indian ink or very strong tea can be applied over the glaze to highlight the crazing. Please be aware that due to the nature of crackle glazes they are not suitable for use on dinnerware.
