Is this food safe?

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.

What do you mean by 'a 30 minute soak'? I'm new to pottery making.

Once it reaches its final temperature say 1040oC, you can hold it there for a period of time ranging usually from 10 minutes to hours in some cases, this is know as a soak. It helps even out the temperaure inside the kiln so if there was a difference between the top and the bottom of the kiln it helps make it the same, hope this helps.

Hi there, are you able to layer this over other glazes? I ask as I layered it over a black Botz earthenware glaze and to 1040 and it’s come out black. No gold at all. I’m not sure what went wrong. Any advice gratefully received! Thanks

Yes you can layer any glaze however it is difficult to predict the final outcome until it is fired. In this case you may want to try applying the gold thicker on top of the black and see if the result improves. Some glazes work better than others but again it is difficult to predict an outcome until you test it in the kiln.

Can this glaze be brushed on? Thanks

Réponses de Scarva:

Hi, yes - this is a brush on glaze, all Botz glazes are brush-on.
Hope this helps!

Would this glaze work well on your black clay?

Hi, no this glaze wouldn't be suitable for our black clay. Sorry!

Hi I've used this a few times and never comes out looking gold.
I fire to 1200. Used it on terracotta, buff sanded and white clay.
Tried 1 layer, 2 and 3.
What am I doing wrong?

Hi there, Botz's recommended firing temp is 1020 with a 20min soak, max temp being 1040. Hope this helps.

Hi
Botz recommend introducing oxygen to the kiln to get optimum gold effect, but I cant find out when this oxygen is required - during firing as heat ramps up or as kiln cools? I have been advised that my electric kiln may struggle to reach temperature if I leave bung out and open vent during firing. Any advice appreciated. Thanks

Hi there, we would suggest leaving the dampener partly open up and down and that should help.

Hello. I make earrings and i trying put some gold accents on them. My experiments not going well. I put Botz gold paint on half a detail and other half i put a glaze. I wondering that botz gold paint doesnt work on white clay or why it is brown? I put 4 layers on the clay detail and nothing is happening, all the time is brown. And next

Hi, for gold accents on pieces such as jewellery we'd recommend looking at gold lustre and third-firing rather than a gold glaze. Hope this helps!
