Speaking of crucibles Will, about a month ago I made an Inconel crucible out of that 601 - 0.10" thick material that I have. Casserollers Ben and Jimbo made a lil foundry following this instructional video-
They melted and blew apart their crucible that was made from the bottom of a fire extinguisher, so I made them one out of Inconel. Just roughly rolled it, cut a circle for the bottom and welded it all up.
They haven't had it up and running again but I'm sure it will work great. They have been melting aluminum cans so I made it big enough to fit a tall boy can inside. If a shot glass size is $75 this one would be pretty damn expensive.
