Lewisite is primarily a vesicant (causing blisters). It secondarily irritates the lungs and is a systemic poison. Upon contact with the skin, it causes large, painful, fluid-filled blisters, especially on the extremities, back, and scrotum.
Titanite is CaTiSiO 5, a yellow or brown mineral that forms characteristic wedge or lozenge-shaped crystals. (more below). Titanite is typically found in calcium-rich metamorphic rocks and scattered in some granites. Its chemical formula often includes other elements (Nb, Cr, F, Na, Fe, Mn, Sn, V or Yt).Titanite has long been known as sphene. That name is now deprecated by the mineralogical authorities, but you may still hear it used by mineral and gem dealers, collectors, and geological old-timers.Other Primary Minerals.more below).
