A few questions:
Which is the better and the short burn process for 4" x 6" flasks in
an electric digital kiln without damage the flasks with or without
IB4m dewaxing the flasks, I give 1 hour to the flask before put it on
the kiln to burn. I normaly put the flask with the sprue base down to
let the wax go down…
When should I “turn the flask”, to let the gases go out? any
I have to practice my english!
