Hello all. I'm new to casting and need some help identifying this alloy. I suspect it's linotype just because of the block lettering but I'm not sure. Different fonts and sizes of letters on the blocks. It's not magnetic, very heavy, it's brittle (breaks off in pieces without bending) and it's crystallized looking where it breaks off. I don't have a hardness tester and haven't melted any yet. Wanted to get some input first before casting any of this. Any help would be greatly appreciated. Thanks in advance.
