Default To SnapRJW: Ochre

Hello Rosemary,

Ochre occurs 40Km to the west from here. I have now discovered that this probably is Mthoba which is the root of a plant that they dry and grind to a fine powder. While they are still in the field school over the Christmas-New Year period, their faces are made white for which they use kaolin, a white clay that occurs around Grahamstown, 70 Km from here, and possibly the only place where kaolin has not formed directly from the weathering of granite but from the Dwyka diamictite which is a glacial deposit derived from a granitic area very far from there. They also use a commercially available product, calamine, as a whitening but I do not know what it is made of.

Best wishes.
