What is a light stone, what kind of stone is a light stone

Light stone. Is a texture term composed of a piece of volcanic rock that is a hardened foam.

microvesicular

Glass. Volcaniclastic rocks.

Walls with very thin, translucent bubbles.

Extrusion. Igneous.

It is commonly, but not exclusively, silicon or felsic to intermediates in the composition (ie.

rhyolitic, dacitic, andesite feldspar, pantellerite, rattle, basalt and others constituting coarse-faced rocks), but occurring is known.

Light stones are commonly pale in color, ranging from white, cream, or gray, but can be greenish-brown or black.

It forms gases that are formed when exsolving from the clay magma which is not possible to gladly separate from the clayed magma before cooling to the glass of the clayed magma nucleate.

Light stone is a common product of explovie eruptions (Plinian and Ignimbrite formation) and commonly forms areas in the upper part of the silica lava.

Light stone has an average.

Porosity. 90%, and initially floats in the water.

Metal slag. Unlike light stone in the walls that are denser, WTH larger bubbles and thicker bubbles;

It sank rapidly.

The difference is the formation of metal slag as a result of the lower viscosity of the magma.

When huge gases are present, the result is a light stone beautiful granular variety known for its beauty.

pumicite.

Light stone is considered a

Glass. Because it doesn't.

Crystal structure. Light stone varies in density according to the thickness of the solid material between bubbles;

Many sample floats.

Water. After **.

Krakatoa drifts through a light stone raft.

Pacific Ocean. 20 years, when the trunk floats among them.

Light stone is versatile to do lightweight.

Specific. or insulative low-density 'breeze block' type bricks.

When used as an additive.

Cement is called a fine-grained version of light stone.

pozzolan

Mix with. Lime.

Form a lightweight, smooth, plaster-like image.

Specific. This form of concrete was used back in the day.

Rome. Period.

It is also used as:

abrasive, especially in polishes, cosmetics.

exfoliants, and for sand-washed jeans.

"Pumice" is commonly used.

Salon. During the period.

pedicure

Remove the process of drying and remaining ** from the feet as well as calluses to the bottom.

Delicately ground light stone is added to some toothpaste and durable hand cleaner as a mild abrasive.

Perhaps the most well-known product advertised containing light stone is.

Lava soap. It is a piece of durable hand soap, sold in bar and liquid form, for mechanics and people who get very dirty hands.

Light stone, also known as pumice stone or pumice rock, is named because of its large pores and small bulk density (it can float in water. Light stone is a porous, lightweight, vitreous acid volcanic eruptive rock with a composition equivalent to rhyolite. The surface of light stone is rough, the bulk density of particles is 450kg m3, the loose bulk density is about 250kg m3, and the porosity and water absorption rate are 50-60%.

Light stone is mainly used as a breathable and water-retaining material in horticultural planting, as well as a soil loosening agent. It is mainly used as a drainage material in the roof and garage roof drainage, and its good water absorption function can also supplement the water required by plants. It also easily removes calluses and rough skin from the hands and feet, leaving the skin smooth and comfortable.

A type of volcanic rock with a composition similar to basalt.

Porous natural volcanic stone, loose texture, porous structure, water absorption rate of 55%, good air permeability and water permeability. It can float on the surface of the water, so it is called pumice stone, lightweight, so it is also called light stone, with large ion exchange capacity, pH balance, water retention and breathability; It contains calcium, magnesium, iron, sulfur and other trace nutrients, and has a unique effect on succulent root flowers such as orchids and junzi orchids. It is suitable for all kinds of plant cultivation media (can be mixed with substrate in proportion), seedbed and potted plant bottom stone, roof garden row, and water retention layer.

It's also a good thing to be able to get a hairball on a sweater.

Light stone is a light-coloured pyroclastic material with low specific gravity and porousness.

It is mostly siliceous magma containing bubble-containing andesite, quartz andesite, rhyolite, etc.

composition. The pores in the rock account for more than 70% of the total volume of the rock, and only a very thin glass connection is connected between the pores, which can float in the water, so it is called pumice or pumice.

Uses: used as filter and desiccant in the chemical industry.

Catalysts, fillers, carriers of agricultural pesticides and control agents for fertilizers. It can be used as a mixture of cement or to prepare clinker-free cement, and can also be used directly as a building material. It can also be used as a traditional Chinese medicine.

1.Light stone, also known as pumice stone or pumice, is named because it has more pores and small bulk density (, and can float in water. Light rock is a porous, light, glassy, acidic volcanic eruptive rock, which is similar in composition to rhyolite.

The surface of light stone is rough, the weight of the particle unit is 450kg m3, the weight of the loose unit is about 250kg m3, the porosity is 7L 8-81%, and the water absorption is 50-60%.

2.Light stone is used in horticulture as an air permeability and water retention material and as a soil loosening agent. It is mainly used for roof and garage roof drainage.

It has a good water absorption function and can also replenish the water needed by the plant. It can also easily remove calluses and thick skin on the hands and feet, making the hands and feet smooth and comfortable.
