Deorating Slips

Many people buy the white and add their own stain combination. Please remember that slips are based on a white clay powder and so any colour produced will be a pastel version of that stain, brighter with a top glaze applied

Usually applied to greenware.

If applied to bisque wipe bisque ware to get rid of salts produced during the bisque firing.

The salts can reboil during glaze firings to cause problems as well as block the pores that the glaze needs to grip to get a good physical integrity.

Fast bisque firing can trap gasses which then reboil during a glaze firing expanding and splitting open ware, bloating and warping; as well as creating pin holes, crawling and peeling off glazes.

Slow bisque firing can solve many glaze firing problems. 50oC from 750-950oC is our preferred rate.
