Hi there, this is actually something we have not tried - but certainly worth testing as you might get an interesting result!

Can I add nano stains to this glaze to produce an opaque glaze for porcelain? If yes, how much for a solid cherry red?

Hi, as this is a white glaze you will get a pink if you add red stain. If you use our GZ2305 porcelain transparent and add red stain at 6-8% you will get a red. To stabilise the red you may need to add some Zirconium Silicate at 2-3%
Hope this helps

Can this glaze be used on domestic ware? Has it been tested for dishwashers/microwaves?

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 the glaze mentioned it is unlikely it would pass a food safe test as bacteria can can easily grow in the craze marks left in earthenware glazes. The most suitable glazes for functional ware are stoneware and glossy fired in an electric kiln and to the suggested temperatures.

Glossy very white and opaque. Very durable only suitable for use on porcelain clays.
