I’m wondering if anyone out there has much experience with
making models of plastecine and making an investment mold then
filling with wax to make a model for casting. I tried this
technique tonite from a good book on wax modeling but haven’t had
success with getting a good wax cast from the investment mold. I
used Ferris Green wax as suggested and glycerin coasted the mold
and heated the mold. I probably heated the mold too hot and the
wax bubbled and got swiss cheese for a model. I tried again with
just a warm mold and didn’t get a fully filled in model. I’m not
a great wax carver and was hoping this technique would free me to
make some more imaginitive pieces since plastecine is pretty easy
to work. I got some sculptor’s clay but its very sticky and not
too easy to work. Maybe I’ll try filling the mold with wax chips
and melting them into the mold in my kiln, but any suggestions
would be helpful as this technique looks promising…Dave
