About VolaschioiteHide

Fe4(SO4)O2(OH)6 · 2H2O
Yellowish orange
Vitreous, Resinous
Specific Gravity:
3.03 (Calculated)
Crystal System:
Named by C. Biagioni, E. Bonaccorsi, and P. Orlandi in 2011 after the ancient name of the type locality, Forno de Volaschio. Forno means furnace. Volaschio has two possible origins. The first is for a hospital, the Hospitale de Volaschio, from the 12th century. The second is that is it is for a man named Volasco who first worked iron at the deposit.

Pronounced volaskioait.
