Mountainite
Mountainite is a rare hydrated potassium sodium calcium silicate mineral with the chemical formula KNa2Ca2[Si8O19(OH)]·6H2O. It belongs to the inosilicate class and is part of the Strunz classification 9.GG.10 and Dana classification 77.2.3.1. The mineral typically exhibits a vitreous to pearly luster, with a hardness of approximately 4.5 to 5 on the Mohs scale. It has a relatively low density and is usually found in white to pale yellow or greenish colors. Mountainite is notable for its fibrous to prismatic crystal habit and is classified as a phyllosilicate due to its sheet-like structure and water content.

Etymology
Mountainite is named after Edgar Mountain, in recognition of his contributions to mineralogy. The mineral was not formally described after 1959 and retains its IMA grandfathered status.
How to recognize it
Mountainite can be identified by its low hardness of 4.5 to 5 on the Mohs scale, which is relatively soft for a silicate mineral. It typically exhibits a white to pale yellow or greenish color and a vitreous to pearly luster. The mineral has a low density and may show a white streak. It is often confused with other fibrous or prismatic silicates, but its chemical composition and crystal habit help distinguish it.
Trivia
Mountainite is notable for its unique chemical composition, which includes a high water content and a complex silicate structure. It is a rare mineral with limited documented occurrences, making it a subject of interest for collectors and researchers. Its fibrous to prismatic crystal habit is uncommon among phyllosilicates, adding to its distinctiveness.
