Greetings good people please help me. I am an apprentice potter who's master works almost exclusively in porcelain and I've stained her plaster wedging table with a completely different clay body. I don't know it's name but it's a red clay, much stiffer, which fires to cone 11 where her porcelain is fired to cone 6. Is there a way to clean the pigment out of the plaster, and if I can't is there a risk it will contaminate her white clay in the future, will the pigment dredge up out of the plaster as she wedges? Part if me thinks it's harmless but I'm afraid I've ruined her table. When I've made reclaim in the past white crystals have formed on the surface as the plaster dries, will the red remove itself that way if I add water to the affected area? I really don't know what to do.
