In Topic: Cone 6 Stoneware Vs Cone 6 Porcelain?

Yesterday, 06:17 PM

I use Standard 365 for everything, from small 3/4 pound cups to 45 pound planters. It throws great and is pretty forgiving for a porcelain. Yes, it must be quite thin to go translucent. The thicker a porcelain can be and still go translucent, the more prone it is to issues like slumping, warping and cracking.

 

I have seen translucent porcelain that uses EPK, a domestic kaolin. English Grolleg is not a necessity. It's more about formula and glassiness.

Not really, besides my own satisfaction in getting the pots really hot and that is how they fired when I was learning. I am really thinking of moving down to cone 6.

 

Could I move down to cone 8 or is there a reason why most people go cone 6? I never realised there was no benefit firing electric in this way.

 

At cone 8 your clay will be underfired or overfired. Dropping down to cone 6 isn't so difficult. Some cone 10 glazes can get there with less than 5% boron frit added. And since you're already firing in oxidation you shouldn't get any big color shifts.

Any particular reason you're firing to cone 10 in an electric kiln? Your elements will last twice as long at cone 6. And since you're not reducing you're not getting any benefit from firing that hot.

Yep, different ingredients take in water differently. I used to make 9000-9500 grams batches when I was working in cone 10. Now most of my cone 6 glazes are 8500 gram batches due to their higher clay content.

Yes, cone 6 porcelain can be translucent.
