Pumice has remarkable abrasive qualities that allow it to be usedin many places. We see it used as a dental abrasive, an abrasivehand soap ingredient, an ingredient in polish, and a cosmetic skinabrasive. Pumice is also used commercially in several ways in construction.It can be used in landscaping… and as a soil conditioner. We alsofind it used in insulation and as a additive to concrete.Pumice isalso really light and soft i use it for pillows (MORE)
Pumice is a type of extrusive igneous rock, formed from high silica lava which is explosively erupted from volcanoes. If the amount of trapped gases in the lava is high, vesicular pumice will be formed; thin walled, high in trapped gas pockets, and able to float on water.
Pumice is generally used in dentisty as an abrasive in tooth polishing to remove calculi and tartar from teeth. It's also used in podiatry as an abrasive to remove calluses. Basically, it's a light weight and easy to find abrasive since it's made from volcanic rock.
Pumice is formed by the rapid cooling of gas entrained (frothy) felsic lava which is erupted from volcanoes. If the amount of trapped gases in the lava is high, and cooled quickly enough to trap the bubbles of gas before they can escape, vesicular pumice will be formed, resulting in the only igne…ous rock that is able to float in water.

There are no minerals in pumice, just glass, but there is a high level of silica.
6 on Moh's scale, less hard than quartz. Actual hardness dependns on composition , which may vary
Pumice is full of holes called vesicles formed from gasses escapingthe molten rock. The holes greatly reduce its density.
Pumice is formed when lava cools very quickly ABOVE ground. The vesicles or tiny holes all over are formed when heavy amounts of gas escape from the lava while cooling, leaving those air pockets. Even though it doesn't seem like it, pumice has a glassy texture just like obsidian glass, both of which… form in very similar ways. (MORE)
Pumice is an igneous rock that forms when magma traps gas bubblesand cools quickly. The gas dissipates and leaves the distinctiveporous nature of the pumice
Pumice is a very light weight rock - it floats in water. It is partof the ejecta of a composite volcano. It may be found in streams oron coastlines nearby to composite volcanoes. If you wanted to buy asmall quantity, then one of the science supply houses would help.
Pumice is considered special because it contains volcanic glass. Itis a powdered or dust form of volcanic rock and the way pumice isformed is very unique.
Pumice is produced in the lava from certain volcanic eruptions. It forms from gas-rich andesitic or rhyolitic lava and has so many gas bubbles that some pumice can float on water..
Pumice can be found around areas of volcanoes that have, or are, producing ejected felsic, frothy lava. Areas surrounding subduction volcanoes are good candidates for the discovery of pumice.
Pumice finds application in dentistry as an abrasive for polishing your teeth. It is used as a bulk filler in wallboard manufacture because it is cheap and light weight. It is used as a plant propagating mix because it can easily be sterilized. It can be used as a spray on fireproofing layer.
Pumice is a textural term for a volcanic rock that is a solidified frothy lava typically created when super-heated, highly pressurized rock is violently ejected from a volcano
Large amounts of pumice are found in Italy, Turkey, Greece, Spain, Canada, and parts of the United States, especially the Rocky Mountain and Pacific Coast states. In many of these locations, pumice is mined to be sold for a variety of uses.
Pumice is usually found around the shore of beaches and rivers, due to the lightness in weight.
Pumice is a form of volcanic glass that is rich in silica. Thereare also fairly high amounts of aluminum oxide, sodium oxide, andpotassium oxide. The holes or vesicles are the remnants of gasbubbles that formed when the pumice was still molten.
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 CO 2 ) dissolved in the lava, so that they rapidly exsolve (like the bubbles of CO 2 that appear when a carbonated drink is opened). The simultaneous cooling then freezes the bubbles in the matrix. Source: wikipedia (MORE)
Because pumice is primarily vesicular volcanic glass, it contains no minerals. The ejected molten volcanic rock cooled too quickly for minerals to form. Chemically, it is similar to felsic rock, high in silicon and aluminum.
Because it is formed on the outside of the Earth (hense the 'ex') This means that magma comes out of the Earth and then it cools to form pumice.
Highly vesicular . Light in color . Specific gravity less than that of water . Felsic in composition . Composed largely of volcanic glass
it depends what part of the world you come from. because pumice is a type of rock produced by volcanoes if you lived in a part of the world where ther are lots of volcanoes then no it would not be a rare substance but if you lived in a part of the world that ther was no volcanoes then pumice would b…e rare . Pumice is not rare it is a very common volcanic rock. (MORE)

Pumice is a disordered material, a result of quick freezing of a boiling glass, and is irregular in all directions. It has no preferred cleavage direction, and indeed is not classed as a mineral, for it lacks both a single chemical form, and a defined crystal arrangement. The pumice with which I'm… most familiar is white to light yellow, but depending on the source material, it will be darker as the magma component is increased. Scoria is a more magma-rich form, and is denser than the white variety. (MORE)
Pumice is used to clean teeth from their dental plaque. Also used to smooth callus and other rough areas on feet.
Pumice forms when an erupting volcano releases a lot of magma that contains dissolved gases. This results in a sort of bubble-filled lava foam. When this cools, the cavities left by the bubbles remain in place.
Pumice is a rough, brittle, and crumbling stone. It does not havemuch luster. It is useful for cleaning porcelain and ceramics.
Generally speaking, no. Pumice is made mostly of glass, which isnot crystalline. It may contain some crystal fragments if the magmahad started to crystallize before erupting.
Pumice forms when it is shot out of a volcano. When it gets out it immediately hardens but still has little holes in it so that also gives it the ability to float on water
A light volcanic rock formed from heavier rock which has had gas bubbling through it, forming vesicles. The word has ancient origins, dating back to Indo-European with connotations of "foam".
Pumice is a type of rock that is made up from sand particles.The stones on beaches eroded against each other to produce sand , some sand is dragged out to the middle of the ocean and deposited on the sea bed , animals like fish die and lay here to. Over hundreds of years more sand has been deposit…ed on top and the weight increase on the layer we spoke about then with the high pressure they form the pumice stone and other stones such as limestone.

yes pumice is very rough. it is regularly used to rid of dead or hard skin on the feet. you can buy it from any good supermarket and most remedy shops.
Pumice, being mostly composed of air bubbles, is surprisingly light for a rock. So light, in fact, that it can float on water.
Pumice can be used for many different sources. I know that you use it in dentistry. IT is mostly used to keep teeth healthy by rubbing on it.
There is still a 2% chance that you can get pregnant when using a condom, however you should definitely not wear one if he is wearing one and don't ask him to put two condoms on because the latex rubbing against itself will tear very fast.
An igneous rock where small bubbles of gas have permeated it to such a degree that the rock is relatively lightweight and delicate to the touch. Pumice is commonly used to "sand" down callouses on feet. Check for some in your local drugstore in the footcare area.
Pumice is a volcanic rock. It forms when a volcano erupts gas-richmolten rock. Some of this may form a sort of foamy lava which coolsrapidly from an extremely high temperature, locking the bubbles inplace.
First it is pumice, and it floats because when it forms from cooling lava, little gaseous bubble get trapped inside that are lighter than air.
No. A dike is an intrusive structure, meaning it forms when moltenrock cools underground. Pumice is an extrusive rock, meaning thatit forms when molten rock cools after being brought above thesurface by a volcanic eruption.
yes because it works well not all of them but most of them do byjashni
No. However there is a similar rock to pumice called scoria, which is sometimes red.
the shape is like a dog and a cat together in a bucket of warm water with soap and dirty dirty dog poo and cat poo
Pumice is widely used to make lightweight concrete or insulative low-density breeze blocks. When used as an additive for cement, a fine-grained version of pumice called pozzolan is mixed with lime to form a light-weight, smooth, plaster-like concrete. This form of concrete was used as far back as Ro…man times. Roman engineers used it to build the huge dome of the Pantheon and as construction material for many aqueducts. (MORE)
Pumice forms when a volcano erupts gas-rich material. Some of thismaterial forms a sort of foamy lava, filled with gas bubbles. Thiscools rapidly and solidifies with the bubbles left in place,forming a highly porous rock. In volcanic rock this texture iscalled vesicular.
No. Clay consists of highly weathered material. While somecomponents of pumice may by re-worked into clay, it will have longsince ceased to be pumice.
Not usually. Pumice is usually light in color. There is a simillar,denser rock called scoria, which is often black.
Pumice is a lightweight volcanic rock filled with holes. It has alow enough density that it floats in water. Pumice is technically aform of volcanic glass. Explosive volnic eruptions are driven bythe expansion of gasses trapped in the magma. Pumice forms fromglobs of foamy lava ejected into the air.… These globs coo andharden rapidly, now allowing any crystals to form, and keeping thegas bubbles in place. (MORE)
This question is highly subjective. Many people feel that cashmere is very fashionable on men. However some disagree, and think it is tasteless. It is a matter of personal opinion.
Pumice comes from volcanoes. The holes are formed in the moltenrock by gasses trapped underground. As the rock cools andsolidifies, the gasses escape - leaving the holes behind.
