Thin, colorless and transparent flakes of sassolite, sublimated on a rock picked up in a high-temperature fumarole field. The interference colors of the reflections show that the flakes are very thin, just a few hundred nanometers. Sassolite was identified by visually comparing to similar, but larger specimens from the same locality that gave a ...

A white patch of colorless sassolite covers the ground below a small low-temperature fumarole that is surrounded by yellow sulfur needles. Such sassolite patches can only be seen after several days of dry weather - sassolite is water-soluble. The position of the white patch is typical, on a slope it is usually situated below the fumarole orifice. ...

Transparent sassolite plates with a white, unamed mineral from the hydrolysis of barberiite crystals. Barberiite reacts with atmospheric water to produce a hydrogen fluoride gas phase and a solid phase that has been reported as NH3BF3OH. The stereochemistry is unclear. This specimen exemplifies the appearance taken on by specimens of barberiite ...

A white to milky-white aggregate of Sassolite composed of numerous thin platy crystals forming a compact massive specimen. The crystal surfaces display a soft pearly lustre with characteristic layered and foliated growth typical of low-temperature evaporitic boric acid deposits. Because Sassolite is highly water-soluble, well-preserved natural ...
