I have fired at 1200C and I get a much darker almost brown orange with very dark brown areas full of pinholes, what would you advise?

This glaze is sensitive to temperature. I would advise dropping another 20 degrees and see if the result improves.

Is this glaze foodsafe?
|
Réponses de Scarva:

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. Ideally a food safe test would be carried out by a reputable body like Lucideon. In the case of the glaze mentioned it would most likely pass a food safe test providing it was fired on a suitable body like our ES5 Original in an electric kiln and to the recommended firing temperatures.

My local class fires stoneware at 1280C, what would happen to this glaze at that temperature?

Réponses de Scarva:

Hi,
Unfortunately this glaze will not work at 1280°C as it will run off the piece at that temperature.

Your firing temp is cone 4/7
4 is a lot cooler than firing higher even at 5 in my little kiln
Can I fire at 1060’?
|
Réponses de Scarva:
|
This glaze will not melt enough at 1060oC you would need to fire to at least 1160oC for the glaze to melt and become glossy. Hope this helps.

Yea I understand this glaze needs to fire at 1160 at least but if it is on top of a pre fired glaze that fires at 1060’ what happens and what is the best firing temp then? Thank you so much

So you want to put a stoneware glaze on top of an already fired earthenware glaze and fire higher? If so the earthenware glaze will melt significantly and most likely run of the vessel, it is hard to predict the result but I would do a small test first and place inside a bowl or on an old kiln shelf incase the glaze runs alot.

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.
