In Topic: Vent Not Turned On During Bisque

26 June 2015 - 03:05 PM

The vent is for the wares and the potter but since the clay is now sintered, rebisque fire will not get any more of the potential problems out; once sintered, the clay cannot release those gasses until near top temp when the clay is as close to molten as it gets.

In Topic: Clay For Sculpting Vs Throwing

Hi Rebeka :

It reallly is all about the grog content: otherwise no big difference.

Some sculpture bodies, especially for those who make super large things may have Kyanite as well which is an odd material that actually gets bigger not smaller when fired.

The grog (and Kyanite) is really about restricting cracking that can happen with a thick thing from shrinkage.


But in general, take your favorite stoneware or eathenware, add 10-15% grog and there is your sculpture clay

In Topic: Glaze Firing Slow Down Between Range Question.

22 May 2015 - 01:24 PM

no point in slowing in the glaze fire: the clay is sintered so gasses cannot escape.

Do a hold in the bisque fire at about 1500 (sintering starts at 1600) for 2 hours ideally.

Loose stack for the bisque, don't tumble stack the dark clays

Sharp little volcano bubbles come from either cooling to quickly or from overfiring the glaze.
