Slips, Engobes and Terra Sigillatas - Alfred's Clay Store

Vitreous slips• Halfway between a glaze and a slip– Less clay/shrinkage than regular slip• 10-20% clay for suspension and green strength• Higher non-plastics• Higher fluxes• Can be applied to dry or bisque ware– Low clay/low shrinkage– More difficult for wet applications because of high flux/lowclay/low green shrinkage• Can be used alone as a functional surface– Very vitreous / almost glaze-like• Think of these as slightly underfired opaque glazes• Can also be used under glazes to influence texture andcolor of glaze
