Description
Scandium rarely circulates as free metal, and dendritic material is the form collectors ask for: feathery, mirror-bright crystals grown during vacuum distillation. This lot came to the collection as a sealed vial and has been stored dry since; the faces show only the faint straw tint scandium takes where air has reached it.
Each piece is weighed and packed in a glass vial inside a foam-lined box. Sold by mass rather than by piece, so the crystal count in a 5 g pack varies.
