Volcanic lapillus, volcanic lava 20/70 mm (c.ca 1000 kg - 1000 lt)

VOLCANIC LAPILLO, VOLCANIC LAVA 20/70 mm (c.ca 1000 Kg - 1000 lt).

Pumice and lapilli are the product of explosive volcanic eruptions formed following a violent expansion of the gases dissolved in lavas of acidic chemical composition: the rapid cooling of the rock prevented the crystallization of the same, trapping the gases inside and generating minerals alveolar expanded more or less accentuated.

In fact, during the solidification phase, the vapors present in the magma, suddenly released, caused the swelling of the entire mass of the magma and during this rapid cooling phase the differences in the physical structure of the various volcanic aggregates were determined: the volcanic lapillus formed from a magma with lower silica content.

The lower viscosity and the slower cooling of the lava facilitated the escape of a certain quantity of the gases present in the magma.

Minerals were formed characterized by vacuums with an average diameter greater than those of the pumice but with a much smaller number.

NB: NEWS ON PACKAGING AND ON THE QUANTITY OF MATERIAL

It should be noted that the inert packaged by the manufacturer in big bags (big bags) that can vary in shape, type and color depending on the availability on the market (therefore the photograph of the big bag is completely indicative: it is the only container of the material) . The aforementioned big bags contain material that has a variable weight depending on the humidity contained (due to the climatic conditions during extraction inside the quarry) and according to the specific weight of the material itself (which varies according to the extraction point at the inside the quarry: the material, being of natural origin, has chemical-physical characteristics that may vary slightly during the geological period of formation). For this reason, there may be variations in weight (both by default and by excess) due to the reasons listed, but always assured that the volume described in the title of the advertisement (therefore the number of liters) will be received by customers. This volume is determined by the manufacturer as COMMERCIAL VOLUME according to UNI EN 12580. We therefore reiterate that the weight described only and exclusively inserted for indicative purposes to quantify the cost of shipping which is calculated on the basis of the total weight.
