Rhyolite is a fine-grained igneous rock which is rich in silica
From German Rhyolit, from Greek rhuax lava stream + lithos stone
Coarse Grained Rock, Opaque Rock
Aphanitic, Glassy, Porphyritic
Decorative Aggregates, Homes, Hotels, Interior Decoration, Kitchens
As Building Stone, As Facing Stone, Paving Stone, Office Buildings
Arrowheads, As Dimension Stone, Building houses or walls, Construction Aggregate, Cutting Tool, for Road Aggregate, Knives
Gemstone, Laboratory bench tops, Jewelry
Pumice Rocks, Obsidian Rocks, Perlite Rocks, Porphyritic Rocks.
Acidic in nature, Available in lots of colors
Rhyolite is a felsic extrusive rock and due to its high silica content, rhyolite lava is very viscous and is volcanic equivalent of granite.

Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite
Has High structural resistance against erosion and climate, Very fine grained rock
Mugearite forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.
