Pure alumina crucibles excite me! How the heck are they made? Can they be slip cast then fired like other ceramics? If so, this puzzles me, since other ceramics rely on a mix of materials to dissolve eachother and fuse. If you heat alumina enough to fuse it, wouldn't it melt and sag and be useless? Perhaps extremes of pressure, no water, high temperature? But then what material could withstand alumina temps which are, what, around 4000 F? Thanks alot!!!
