Notorious Lyear
Sorry, I underestimated the language barriers between hardware store/interior architecture/hospital speak . I was referring to the gypsum stuff with which one fills holes in the walls after ripping out Fischer wall plugs, or similar minor corrections around the house.
This 20% castor soap is bright white, with a dull/matte surface. It feels waxy when dry, and wet it has a grip that reminds me of blackboard chalk (which is incidentally made from gypsum as well these days). It is remarkably hard, but with a terrible longevity (the piece at the top left used to be just as thick as the others, I just used three times for lather tests).
