Sphalerite is the chief ore of zinc. It consists largely of zinc sulfide in crystalline form but almost always contains variable iron. When iron content is high it is an opaque black variety, marmatite. It is usually found in association with galena, pyrite, and other sulfides along with calcite, dolomite, and fluorite. Miners have also been known to refer to sphalerite as zinc blende, black-jack, and ruby jack.

Night Bike - ordered the paint right after I saw it. Since the boy dresses in such dark clothing, this will make him visible...which will make me happy for safety sake and him happy that I will let him ride the bike when it is dark (since it is dark at 5 in the winter)
