In the mean time, here's his thread .

i bet if bruno were to cut deeper into the base of a casting (say .5" or so) then he to would discover air pockets visible without a microscope. there is NO WAY to pour copper without getting air pockets in it, other than to control the atmosphere that its cast in. or to cast it in really thin peices which still results in air pockets, although very small.
Absolutely NO WAY. you cant beat physics man. i dont care how determined you are!
the thinner the peice cast ,the less air molecules...hence, smaller air pockets that may not be visible to the naked eye. now take that same peice that you cast thin , and look at it under a microscope. thats a lotta pockets huh?
please somebody prove me wrong
