Pumice is created when super-heated, highly pressurized rock is violently ejected from avolcano. It can be formed when lava and water are mixed. This unusual formation is due to the simultaneous actions of rapid cooling and rapid depressurization. The depressurization creates bubbles by lowering the solubility of gases (including water and CO2) dissolved in the lava, so that they rapidly exsolve (like the bubbles of CO2 that appear when a carbonated drink is opened). The simultaneous cooling then freezes the bubbles in the matrix.

What else can I help you with?
Does pumice have large or small crystals?
Pumice does not have crystals. It is made of glass.
Is pumice inorganic?
Yes. Pumice is inorganic. It is a glassy volcanic rock made mostly of silicates.
Which islands are made out of pumice?
Canary Islands.
Is pumice a element or compound?
Pumice is neither an element nor a compound. It is a type of volcanic rock that is made up of various minerals and volcanic glass.
What are pink pearl erasers are made of?
Rubber and pumice
What age is pumice stone?
Pumice stone does not really have an official age. It is typically made by factories and used as a beauty product for feet.
Why does pumice have no crystal structure?
Pumice is made of glass. Glass forms when molten rock cools too quickly for crystals to form.
What is made out of pumice?
Pumice is a form of volcanic glass that is rich in silica. There are also fairly high amounts of aluminum oxide, sodium oxide, and potassium oxide. The holes or vesicles are the remnants of gas bubbles that formed when the pumice was still molten.
Do statues made of pumice erode away?
Yes, statues made of pumice would be susceptible to erosion over time due to its porous and brittle nature. Pumice is a lightweight, frothy volcanic rock that can easily break down when exposed to environmental factors like moisture, wind, and temperature fluctuations, causing it to gradually wear away. Regular maintenance and protective measures would be needed to preserve pumice statues.
Where can you find where pumice was made?
Pumice is formed from volcanic eruptions, specifically from the rapid cooling and depressurization of lava that is rich in gas. To find where pumice was made, you can look for areas with active or historically active volcanoes, such as the Cascade Range in the United States, the volcanic regions of Italy (like Mount Vesuvius), and the islands of the Pacific Ring of Fire. Geological surveys and volcanic activity reports can also provide information on pumice deposits.
Is pumice white or is pumice gray?
Pumice can be white, gray, or even pink.
Which stone floats in water?
Pumice floats on water. It is because it is made out of lava which had bubbles left inside it. The bubbles has air trapped in it. These bubbles allow pumice to float on water.
