I had a student do a large sculpture of an otter with it (wet set clay) It
shaped well and did what she wanted but when we soaked it to harden it it
got oozy oily and made cracks where they were not wanted. My guess is that
it was the size of the piece, Smaller is probably better. It did not take
paint all that well due to the oozy oil....
Yes, the size was too big. An outer shell is all that hardens, the inside
does not. When curing, put ice cubes in the water. The water turns warm from
all the clay put in it, the water MUST be ice cold. If not, the pieces break.
Wash the pieces with Dawn detergent.
