Will Scarva terra color glazes go over Craft Crank?

They will however the iron content will effect the colours and most will graze as well.

I use this glaze over nano color decorating slip. This works lovely. It doesn't run and gives a lovely finish. It is very delicate layer and i was wondering which is your most toughest clear transparent glaze, because I'd like to try a few more of your products, thank you!

We used your Nano colours underglaze with spectrum underglaze dipped in stoneware powdered glaze glossy transparent, the problem is that the finish is not glossy and when applied thicker it left a milky look on the pottery. We fired 1220c.If you could help us get this right we would really appreciate it, thank you.

Transparent glaze works best when applied thinly. It is normal when a transparent glaze is applied to thickly it will go milky. As for not being glossy, was the glaze purchased in powder form and if so was it passed through a sieve? What temperature was it fired to on the computerised controller and on what type of clay? Look forward to hearing from you.

If this glaze was to be applied over a white slip which has had cobalt carbonated decoration upon the surface fired in, what would be the best temperature to fire it to, to bring out the cobalt coloring and get the glossy finish too?

Fire at 1220oC on a computerised controller for best results.

Hi, could you please tell me what the difference is between this glaze and Terracolor 603 Glossy Transparent? Are they both tableware safe?
|
Scarva Replies:

603 Transparent is more fluid than 606. 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. The most suitable glazes for functional ware are stoneware and glossy fired in an electric kiln and to the suggested temperatures.
