Can I turn forged ingots into alloys?

[Frobresh]

In the interest of aesthetics I turned all of my zinc, bismuth, and copper into ingots and made lovely neat piles.

I now want to turn this into bismuth bronze tools, armour, etc.

I am likely missing something, but I can't see how to do this in game.  I cannot add them to a crucible, adding them to the furnace as individual ingots wont smith an alloy, and I'm not sure of another method to smith.

 

Thank you for any help, please tell me I didn't smith 100's of ore into 10's of bars and now they are pretty much functionally useless!

Use a chissel to break down cast items into metal bits, which can then be melted down like ore.
