Could you change the spent non-expendable mold by the Foulded Reusable Mold recently introduced by angels smelting, so that all recipes return the same kind of used mold?

I would but that would mean having to use an engine for each mold, im considering options including doing the same system, but with an iron gear to great a "gear" mold set

I have done an update, and i am not going to have the same kind of spent mold, that could lead to some interesting exploits, considering mine don't "break" like angels ones

What happens with angels ones? They didn't break in my game.

there is a chance to not return the reusable mold

When cleaning them, I see

Ok, different angle, Could you replace all indispensable molds by your version of them?

Ok, you already have, my bad
