Finally.. plaster batts for wedging

So this was an attempt at reconstituting some clay from a bucket load of failed pots I soaked and mixed into mud with a drill mounted paint mixer. Plastic is likely the worst drying substrate but I really thought air drying the surface would work. It was out for the better part of a week with little improvement (drying).

 

 This is what I have been wedging on  (leftover drywall). It's not long before the paper facing starts to shed into the clay. It would last longer with canvas stretched over it but plaster works best. The plaster batt at the top of the picture was the failed first attempt at casting a batt. I used warm water and the plaster set up faster than I could get it leveled in the frame I had built for it. It was like leveling cookie dough and the final surface shed plaster bits into the clay. Rather than discard it I have skim coated it with fresh plaster and will use it for drying reconstituted clay. 

 The second attempt proved successful!

A proper wedging table...goodbye drywall!
