Scarva Earthstone Professional PF700 Porcelain White Stoneware Clay From  £23.38

Bought this as reviews say it fires as white as Porcelain. It does but is is awful clay to use. Tried so many different firing times / temps etc but cant seem to stop the clay cracking. It will also crack once out the kiln too after sitting for a couple of days. Will be going back to porcelain, maybe more expensive but never have any problems with cracking etc.

The 1 out of 10 pots that do survive are very nice and white and look lovey with celadons etc. but I cant justify the 10% keeper rate!
