Please let us input items from the top of the foundry lid. Also, please don't make the glass lid only work for alloying and vis-versa.

Hello 👋 @Elnhomantia
This is planned no worries. Create Metallurgy is recent, a lot of thing are not ergonomic and useful for now. I just need to take the time to think about the way I will make the Foundry more useful and practical.
But thanks to take the time to propose your suggestions.

I also have another sugestion, with the bassin you added, maybe doing like the create tank, making a sort of multiblock with a max size of 3*3*3, would bo cool

Of course, this is planned no worries, take a look at Mod page planned features list.

Hey @Elnhomantia 👋
