It began to be used for cosmetic purposes in ancient times, when mankind had not yet invented soap. The stone clot was ideal for removing dirt from the skin and helping women in the fight against excess vegetation.

On the this moment there are two types of pumice:

• Natural - volcanic natural stone with a porous structure that does not cause allergic reactions. The material gently removes rough tissue. Leaves no injuries on the skin.
• Artificial - made from polymeric materials, which gradually wear off over the course of their service life. Safe, easy to use.

Both options are available and can be found in household chemicals and cosmetics stores.

What material are they made of

Natural pumice is a natural stone formed from lava. It has important beneficial features: environmentally friendly, hypoallergenic, does not crumble, does not break during the procedure.

For the production of artificial cleaning blocks, the following are used:

• artificial polymer - porous, not prone to swelling, retains its shape when exposed to water. The main advantage is that it prevents the development of harmful microbes. Disadvantage - in case of accidental damage skin the inflammatory process develops;
• diamond grit is a durable, expensive material. Has high hardness and low roughness, which makes it possible to use the device in professional and home pedicure;
• glass - quickly removes the rough layer, makes the legs smooth. The disadvantage is fast abrasion;
• minerals (coal, sapphire) - easy to use, effectively cleanse dead cells, give softness and tenderness to the skin;
• laser-cut metal is a tool that can remove any corns, crack, dry corn, and other problems. Has a different degree of rigidity: high - can only be used on a dry surface; medium - suitable for regular use.

Pumice stones are classified according to the following criteria:

• mechanical - looks like a stone, a handle, a paddle and another shape. To cleanse the skin, you need to make your own efforts, that is, rub it by hand;
• electric - works from the network, accumulator, batteries. The electrical appliance cleans by twisting the working surface. Cleaning takes place at high speed, which significantly reduces the procedure time. The result is a smooth, clean heel in minutes.

What is a pumice stone? This formation is a volcanic glass of a porous structure, has a different color - depending on the iron content in it. This porous material can be light yellow, black, and even blue.

This substance is formed in nature at the moment of solidification of volcanic lava... This is a very light material, floating on the surface of the water, it will never sink. It has a very porous structure, due to which the thermal insulation properties of this material are quite high.

Where pumice is mined
