I've read that if you're dissatisfied with the results of a sawdust firing, rebisquing the pots will burn out the carbon and you can then refire them. HOWEVER, I've also read that exposure to salt will harm the elements of an electric kiln. Since I combine salt, Miracle-Gro and copper carbonate in my sawdust firings, this has me wondering:
1) If I rinse my sawdust fired pieces and lightly wet sand them, will that remove enough of the residual salt to prevent damaging my kiln elements?
2) Would combining these refires in a load with greenware negatively affect the greenware?
If more information helps, I use the preprogrammed slow bisque and fire to cone 010 in an electric kiln with a down draft vent system.
Thanks so much for any advice you can give me!
