I want to use something that is faster than ” lost wax casting ” and I was wondering if I could machine a reusable 2 piece mold to pour molten silver in . Let it harden, separate the mold and pop out the unfinished product . I know there might be a proplem with the mold warping , but if I use a mold, lets say each half being a inch or so think . Also what type of releasing agent if any would I use prier to each use of the mold . I was told that talcum powder would be a good releasing agent , but that sounds a little odd ? What i had in mind was pouring about 2 ounces of silver at a time into a mold with the out side diameter of 2″x5″x7″ .

Lipiew asked:


I have a wax figure i would like to cast into metal bColloidald to coat it with some sort of ceramic material except clay to fire melt the wax out leaving a perfect mold for a metal pour. Is this Colloidal silica liquid and I add sand to it or is it the other way around. Or do I need to use something completely different.
