I've read a bunch of older books on casting that tell me I need to keep fluxing my alloy to prevent the tin and antimony from separating out on the top.
Really? Then why does my pot look exactly the same when I'm casting with pure lead as it does when I'm casting with pure linotype melted directly from printer's slugs so hard they ring? I get a thin layer of oxide on both once I've been casting for a while.
Everything I know about chemistry tells me lead and tin and antimony make a true solution when melted together, just like sugar and water. You don't have to flux your kool-aid once you mix it, do you?
Your thoughts?
