Please make it easier to recycle other metal pieces

I have a bunch of metal bits like iron rods which don’t have any use because there’s already more than one and I’d like a way to melt them back into steel or iron ingots so I can reuse them. This is because sometimes I make things at the Newcomen engine by accident and now I have no way of reversing what I just did which bums me out and also accumulates clutter.
