In one place you say it's "VitraClay White Earthenware Clay - Low Fire", in description "White earthenware clay will fire to stoneware temperatures"? The description of this clay is very confusing and does not make sense. Sorry.

Our White Earthenware Clay fires from 1020°C to 1241°C, covering both earthenware and stoneware temperatures.

This is a great, and versatile clay with a smooth texture and fires to a nice white. The temperature tolerance allows for this white clay to be used with both Earthenware and Stoneware glazes. These are tried and tested against our Vitraglaze range with fantastic results.
