something to that effect would work. as i stated before....you cant pour copper without controlling the oxygen content and expect it not to have pockets of oxygen.
and as far as casting thicker but thinning the base........
that would be defeating the purpose. everything copper above the base would not be as thermally conductive because of the high oxygen content, and a very large percentage of the surface area above the base would be useless. you might as well make one out of aluminum.as it would be more conductive for our purposes if poured in the same manner.
look im not trying to rattle anyones cage. im just trying to save the guy who started this thread some time and wasted copper.
i dont really know of a way to cast copper without spending hunreds of thousands of dollars for the proper equipement to do it without contamination. if there were a way, dont you think there would be a hell of alot of companies that make these type furnaces out of business?
i dont know, but logic tells me it cant be done any cheaper.
