Clay from below a bog, ready to throw right out of the ground!


Thursday 9th January 2014

This little pot on the left is more than it appears. Both of these samples were fired at cone 01 and clear glazed in the green state (without bisquing). The one on the right, a typical unprocessed native terra cotta clay, is full of pinholes, the one on the left has none. But the one on the left has been pre-processed by mother nature: it is from a thick layer of clay found below a bog in northern Alberta. It has 21% water content, you just cut a piece out, wedge it and throw a pot! Although it contains some particulate, it is highly plastic yet dries well and fires to a dense stoneware-like hardness 11 cones lower than we normally make stoneware at.
