Castalot for repeated firings??
Posted: Wed Aug 13, 2003 6:26 pm
Anyone tried the new product called Castalot??
(a re-useable mold material that can be used for mulitple firings)
So far I have turned up with 5 repeated castings from the first molds I made but I havent been satisfied with the finish on the glass.
The manufacturer recommends using kiln wash to coat the inside of the mold - They recommend it make the mold to hold up longer. It leaves a grainey finish on the glass. So on some firings I didnt use Kiln wash and the mold material stuck to the glass (but only a few- and some others were beautiful!) and thus hurting the mold for repeated use.
Anyone had success with a good finish and repeated firings??
Care to share the ratio of water to mold material that works best for you??
