Galena cube
Galena typically displays a gray metallic luster and forms cubes or octahedral crystals. The chemical composition of galena is PbS. While galena will not pose a health hazard by sitting on the shelf, or even from casual handling, we suggest washing hands following handling due to the lead content of the mineral. Precision: Galena weighs 7.6 gram per cubic centimeter or 7 600 kilogram per cubic meter, i.e. density of galena is equal to 7 600 kg/m³. In Imperial or US customary measurement system, the density is equal to 474.45 pound per cubic foot [lb/ft³], or 4.39 ounce per cubic inch [oz/inch³] . Melting Point (MP), Galena changes its state from ...
