Sibelco 3520: Nigra 10kg

Unfired characteristics: A coarse clay body to touch, grey in colour when wet.

Working notes: Performs well as slabs although it will have rough edges due to the grog content. The addition of grog makes it especially strong for hand building and sculpture. The larger particle size will give it a textured surface when fired.

It will start to turn black at 1150°C and will continue to mature at higher temperatures.

The shrinkage is especially low for a body of this type.
