Information about Tachylite
Rocks are naturally occurring solids which are composed of minerals & have been used by humans since ages. From Stone Age, rocks are used for various purposes. Also, the metals and minerals found in rock play an important role in our life. Get to know all the Tachylite Uses. We have provided you with all information about Tachylite rock here. Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt. Tachylite is available in black, dark brown colors. The streak of a rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Tachylite is vermilion.
