"Can I put my plaster wedging board in the oven on warm to help dry it
out,
or would that break it down?" Leigh Whitaker.
Hi Leigh,
I do it all the time. For new molds or plaster bats etc.
I put the plaster on the middle rack of my oven, set it to "warm" or
the lowest setting.
I've let plaster set in there for hours. Works fine. I've even taken
the pieces out hot with gloves, no thermal shock.
It saves days of drying.
A story: Once I decided to dry out a plaster mold in my electric kiln.
I forgot about it. When I returned I smelled an acrid smell. The piece
had gotten to 600 degrees! The result was that the plaster had
developed a soft, chalky surface. It was ruined.

Okay, conflicting information! I guess as long as the oven doesn't get too
warm it's all right.
I ended up drying the bat with a fan overnight. It's still a little damp,
but I went ahead and put the clay on it anyway. I think I am going to make
another wedging board and rotate them out so I don't have to worry about it.
I've been needing to make a new one anyway.
Thanks,
Leigh
