Thanks for the replies! Andrew, don't even know what you mean by "burn out cleanly" and I am planning on casting or making a mold of the piece once its done so I probably shouldn't mix them eh?
Mack, I live in Thailand and calling Chavant is more of a problem than its worth, I've tried and dealing with phone cards and wait times is quite troublesome hence why I came here. If I was in the states, I'd have already done this.
Thanks so much again for the help!
