Manufacturer: Scarva

Speckled Stoneware is made using our dry-batching method of production. ES 109 is superbly plastic and has an attractive speckle. Made from a mixture of ball clays with medium textured silica sand added for tooth it will give a reduction effect when fired in an oxidising atmosphere.

This body has been developed for the professional production potter and with good thermal shock properties is excellent for domestic ware.
