Bricks and other products from the sand of the soul

It would be fun to make stairs, half blocks, carved blocks of soul sand. Would have 3 variants: carved, polished and neither polished nor carved. What is it with a polished soul sand block? I am already in a hurry to help, so on this block there would be a gasta pattern (a bit like from a desert block with wethern on it). You could chew on these blocks with a slow spell that would work on them (for the moment)
