Lapillus

Lapillus Quarry

PUMICES and LAPILLI are products of explosive volcanic eruptions formed following a violent expansion of gases dissolved in the chemical composition of lavas acid. The rapid cooling of the rock has prevented the crystallization of the same, trapping internally the gases and generating more or less expanded beehive minerals.

During the solidification, the vapours present in the magma, suddenly released, have caused the swelling of the whole magma mass. During this phase of rapid cooling, certain differences in the physical structure of various inert volcanic materials have been released.

The VOLCANIC LAPILLUS has been formed from a magma having a lower content of silicon The minor viscosity and a slowed down cooling of lava have facilitated the escape of a certain quantity of magma gases. In this way, minerals characterized by vacuousness, having a larger medium diameter than those of pumice but in lower quantity.
