In Topic: Throwing Grainy Rough Clays

I have been throwing some rough raku clay after using only porcelain for a long time. It is rough but stronger to throw than porcelain. I don't know where you are in Italy or what type of clay are available to your. If you want to mis something into a clay to make it rougher, you can try things like used coffee grounds or fine sawdust. They will not feel as touch as chunks of rock.

Read more of his articles. They cover all types of resists down to lipstick. It is different from ceramic sag gars that are fired in a raku kiln and that uses things like copper carbonate and salt. The ceramic saggars for to 1650. The foil saggars in a raku kiln goes 1250-1400 F.It all depends on what your doing. Cow dung is more for a pit firing with pots going over hot coals, then covered with dried dung until it burns through...about 2-3 hours.

Take the stubborn particles and run them in a blender for a while and then try to sieve. You should be able to break it down again.
