I have a few questions though:
I've just bought a bag of ordinary terracotta clay from an arts & crafts shop. I'm sure it's plain, ordinary clay but the colour is a bit paler (more yellowish) than the one in your first post. Do you think this is because of the lower iron content and if it is so, do you think it's still ok to use this clay? What do you think about refined clay, DAS clay or air-dried clay?

Thx heaps
The gray / yellowish clays are fine to use too. Good luck!
