Rhyolite: An extrusive igneous rock. Photos and definition.
What is Rhyolite? Rhyolite is an extrusive igneous rock with a very high silica content. It is usually pink or gray in color with grains so small that they are difficult to observe without a hand lens.Rhyolite is made up of quartz, plagioclase, and sanidine, with minor amounts of hornblende and biotite.Trapped gases often produce vugs in the rock.

Specific gravity - University of Auckland
Specific gravity Definition. A mineral's specific gravity is the ratio of its mass to the mass of an equal volume of water. For example, magnetite has a specific gravity value of 5.2, meaning 1cm 3 of magnetite will be 5.2 times as heavy as 1cm 3 of water. Test. Although this property can be precisely measured, it is often tested by simply hefting the specimen in the hand.

Rhyolite - Wikipedia
Rhyolite is an igneous, volcanic rock, of felsic (silica-rich) composition (typically > 69% SiO 2 – see the TAS classification). It may have any texture from glassy to aphanitic to porphyritic. The mineral assemblage is usually quartz, sanidine and plagioclase (in a ratio > 2:1 – see the QAPF diagram).
