For casting
If you have some piece which does not want to release, & is big, mold it with wax, either in cavity or in relief, because it is malleable once soft & obeys, and thus separates itself from the piece without leaving anything. But take heed that the melted wax be neither too hot nor too cold. Some mold with wax heated in hot water, but in pressing the mold, it becomes gauche & becomes fake. Once your cavity in wax, you can cast in some very soft clay & very moistened & clear, & let it dry at ease. Then you will make a cavity on it ave of lead or tin, in tu which what you will form will be of good release.
