I've been thinking about steam casting copper waterblocks. Molten copper would be forced into a hot mold by the steam at maybe 50-100 PSI. This should help prevent surface cracking and voids, but I'm not sure how much hydrogen and oxygen the copper would pick up. In the usual method, not only does the steam come into direct contact with the metal, the metal is heated in the upper part of the porous mold in a sort of crucible with many small holes in the bottom. (Surface tension keeps the metal in place until the steam forces it down into the mold.) This works great for casting jewelry from silver, but I think casting copper waterblocks might be a bit more difficult.

Any thoughts?
