Just gonna ask real quick… Multiblock crucibles can’t be emptied/filled with jugs like the regular crucible, right?
Because i had grand ideas of sparing me the trouble of “alloying” black sand with carbon to make iron in the multiblock crucible, then solidifying it and re-melting it in the smelter.
I would even use opencomputers robots to do this for me.
That is, i wanted to pick the molten iron up as a liquid in jugs and pouring the molten iron into a drum for later use. But it seems i can’t do that?
And if that’s not “intended” because “the smelter exists for a reason” then to me that’s pretty dumb, i am storing all my metals as molten in drums now (because heck realism to heck) so i can just use it on demand.
So making iron in the crucible only to have to re-smelt it in the smelter is annoying and feels so wasteful. It’s already molten FFS! 
It would be nice if there was at least a late game/high tech way (after one has made a smelter already) to get molten stuff out of both kinds of crucibles into drums automatically.
Or do i really have to use the small crucible for this just because it’s the only one that works this way?
And on that note, do capsule-cell-containers work like jugs do? Because i am going to need them for higher temperature stuff in the future with crucibles. For the stuff that lacks a mixer alloying recipe.
