[QUOTE="Mark Jackson, post: 26900, member: 153"] Charles my man, you make me proud to be a dental technician, One thing I didn't see spoken about was the need to add AT LEAST 50% new alloy to every casting. During casting, there are certain trace elements that are lost, and need to be reconstitued with fresh alloy. With repeated casting of a button, you can alter the chemistry of the alloy, and therefore will observe hevaior you might not not be what you expect, even if you follow the instructions of degassing exactly.
