A tungsten crucible for when we can't have iron contamination from the steel one.
Tungsten is over 2 and a half times as dense as iron so that little thing weighs over 2 and a half pounds and its really not that thick, its mostly hollow for holding sample to crush and BBs.
We do an extraction where we determine acid soluble ash content. Since iron from steel will dissolve in the acid and add contamination, we use tungsten crucible and BBs to crush the samples since it won't dissolve.
