Sibelco 2005: Nigra 10kg

Stoneware: A medium grogged black clay, used for both throwing and hand building. The slightly coarse material allows you to make larger and more ambitious designs. 10% grog/chamotte of 0,5mm.

Unfired characteristics : A medium textured grey body, with a subtle coarse feel. Perfectly usable on a wheel.

Working notes: A good throwing clay for larger pieces, even when pulling thin edges. It produces clean lines and slab builds well, slightly better suited to larger hand building wares. For more on the clays glaze fits, see product attachments.
