“After working with a number of white clays in recent years I have now changed the whole studio to Mid-Fire Porcelain made by Primo Clays. It is a completely universal clay. The body throws well from small delicate pieces through to bottles of over a metre. It is versatile and we use it in its finest translucent form through to large paper clay structures.

It is extremely stable and supports a wide range of glazes including the crazed glazes I am currently developing. In fact it has solved a number of my firing problems and I am very happy to recommend it.”

Some of the best ball clays we have access to are black in their raw state. Even the tiniest particles that pass through our fine screens can be visible in the cut block of clay. These ball clay particles fire white and are not evident in fired pottery.
