Hello, this is my first post so apologies if my question is greener than Robin Hoods long Johns! I have created a plaster (Crystacl-r) mould, originally cast from a newplast (oil based clay like plasticine) sculpt I made. The aim is to paint thickened silicone into it to make some animatronic skin for a creature I'm creating. Anyway, I am having a right old time cleaning the plasticine out of the plaster mould. I've tried casting a layer of latex to pull the bits out, using a hair dryer to attempt to melt the plasticine, using wooden tools to try to scrape it out (which ends up scarring the plaster ) all to no avail. I read somewhere that you can use water and detergent on the mould, but as it is basically a plaster of Paris will this not get absorbed into and ultimately wreck the mould? Can anyone suggest an effective method of cleaning plasticine out of crystacl-r plaster mould, that will not damage the details on the plaster at all? All suggestions welcome... Many thanks in advance! J

I wash everything outside to keep clay from getting into my plumbing. I am going to start glazing and firing at home soon. Should I take the same precautions with cleaning up after glazing? Will glaze cause problems in the plumbing?

FYI for us potters: Note the magnitude of the standards decrease. http://www.nbcnews.com/health/health-news/u-s-lowers-silica-dust-limit-first-time-45-years-n545201 best, ................john

I couldn't find anything via search so here it goes! What kind of maintenance should I be doing for my wheel? How often should I get into it and lubricate? It is a Shimpo, the front says 21 century metal traction drive wheel. It had been cleaned and tuned up (bought used at retail) but I have no knowledge of its on going needs, beyond that machinery can't withstand friction without maintence: so clearly, I need to know! I am aware I could call up my clay supplier and ask, however I just don't want to be the obnoxiously needy customer if I can find what I need on my own! 😊
