Reticulite- A Volcanic Lava Produced in Fire Fountains!

Reticulite is a volcanic rock from the big island of Hawaii! This lava is produced by fire fountains that are charged with gasses ...creating foam that is ripped off and thrown up by wind and blown 10's of miles away.This can create "Reticulite Dunes." Looks very much like "sponge" but it is lava.

Its apparent specific gravity is 0.025g/cm3. Reticulite is a term used by volcanologists. This piece was collected in the 1930's, from an eruption near the Kilauea Craters, Hawaii.

This beautiful specimen comes in 1.25-inch hinged perky, with info.
