This one is surprisingly heavy. A friend tells me that this piece might be pot metal. Thats a new one on me, so Wikipedia to the rescue again. Ah-hah, so its pretty similar to white metal which I am familiar with (as in the generic version, not the code word for silver that my British friends use.) Hmm. The constituent ingredients of either are not really to my tastes; Im going to have to test it to see if this grey is a coating or the actual stuff. Not looking good at this stage. If it is, it will be too soft for what I have planned. It would a good candidate for melting down though I wonder if any of my fellow-artists are planning on casting?
