Description

Firing Range: 1200°C-1300°C

Rokk Grey Grogged Stoneware has been developed for sculptural applications and for outdoors pieces, the high grog content (40% fine grog 0-0.5mm) providing a beautiful textured surface and excellent handling qualities. Depending on the firing temperature this body takes on a range of grey hues. To retain a 'cool grey', fire at 1200C or below. The grey hue can become 'brownish' above this temperature and certain glazes will emphasise this. Supplied in a 12.5kg bag.
