Yep, that's it- - - -90% lead carbonate, 10% Linseed oil. The stuff is usually dried up into a solid mass, so I dig some pieces out with a wood chisel and use a mortar and pestle and linseed oil to grind it to a smooth, thick paste. It makes the best lube for the dead center on a lathe I've ever used, and it works better than Prussian Blue for indicating gear tooth patterns.
