Hi all
Odd question: does the powder need to be talc? I have been using pure talc for a few years. It's not the same as the stuff Prince August sells, but it does do the job.
But what does everyone else use? I haven't really been looking very hard, but I haven't seen pure talcum power for sale for years. (I got mine from friends who are ceramists).
Can you use standard buy-in-pharmacy baby powder?

Normal Baby Powder should work well. The whole purpose is to allow air to escape, so provided the powder is dry, very fine and added properly, the type of powder is not a big issue. Our powder is just excellent, but it is not the only powder that can be used.
Certainly experiment with other powder if you desire, it will not harm the mould anyway, so if a powder is not working out, no harm is done, just remelt any cast and try something else.

how about graphite instead of powder? I cannot be sure how that would work. If it is too fine it will not allow air to escape properly. I cannot see any harm in trying it out. That is normally used for metal moulds for the same purpose so technically it might work, however metal moulds are able to take finer powder because of the solid nature of the material while rubber is a lot softer and bigger granules might be needed.
