    So technically, these aren't "crucibles', but crucible holders; the steel bowls are the actual crucibles...

    That is true. I like the removable bowls because of material contamination and easy pouring. I have a permanent ladle embedded in one crucible I used for the key video. It is 4-5 years old and my goto for zinc. It has developed a crack from dropping but still solid due to internal copper wire.
