I have made a salt dough "house". It is quite flat, but even on the thinnest part I have noticed that it still seems a little soft on the back even after around 15 hours in a slow oven. The problem is I painted the front of it and varnished the front as well. Is there any way I can "dry out" the back of it because if I varnish straight over it then I would be sealing the moisture in. I presume putting it back in the oven is out since the varnish fumes would not be good for us!
