"volcanic, shading into subvolcanic. The terms lava stone and lava rock are more used by marketers than geologists, who would likely say ""volcanic rock"" (since lava is a molten liquid and rock is solid). ""Lava stone"" may describe anything from a friable silicic pumice to solid mafic flow basalt, and is sometimes used to describe rocks that were never lava, but look as if they were (such as sedimentary limestone with dissolution pitting). To convey anything about the physical or chemical properties of the rock, a more specific term should be used; a good supplier will know what sort of"
"Pedicure A pedicure is a cosmetic treatment of the feet and toenails, analogous to a manicure. Pedicures are done for cosmetic, therapeutic purposes. They are popular throughout the world, and especially among women. Pedicures include care not only for the toenails; dead skin cells are rubbed off the bottom of the feet using a rough stone (often a pumice stone). Skin care is often provided up to the knee, including granular exfoliation, moisturizing, and massage. The word ""pedicure"" is derived from the Latin words ""pedis"", which means ""of the foot"", and ""cura"", which means ""care"". People have been pedicuring their"

Pumice Pumice (), called pumicite in its powdered or dust form, is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. It is typically light colored. Scoria is another vesicular volcanic rock that differs from pumice in having larger vesicles, thicker vesicle walls and being dark colored and denser. Pumice is created when"

Stones (usually basalt) are placed into an electric slow-cooker or a purpose-built device which is filled with water. The water is typically heated to . Once the stones have heated sufficiently, some are placed onto specific points on the body (such as the back, hands, etc.) and others are held by the massage therapist and used to work the muscles.

Carved, volcanic-stone ceremonial metates represent one of the most unusual and complex traditions of pre-Columbian artifacts from Costa Rica. They come in many different forms, and morphological variation corresponds to different regions and time periods. They can be rectangular, circular, flat, or curved.

The word temazcal comes from the Nahuatl word (""house of heat""), or possibly from the Nahua words (to bathe) and (house). Temazcal in English is also written as temezcal, temascal, or temescal.

A related texture is amygdaloidal in which the volcanic rock, usually basalt or andesite, has cavities, or vesicles, that are filled with secondary minerals, such as zeolites, calcite, quartz, or chalcedony. Individual cavity fillings are termed amygdules (American usage) or amygdales (British usage). Sometimes these can be sources of semi-precious stones such as diamonds. Rock types that display a vesicular texture include pumice and scoria. Vesicular texture Vesicular texture is a volcanic rock texture characterized by a rock being pitted with many cavities (known as vesicles)"

It takes its name from the eponymous extinct volcano massif, whose main peak is the Monte Urtigu (1,050 m). Extending for some 700 km², the massif had originally a maximum elevation of c. 1,600/1,700 m, later reduced due to erosion. The volcanic origin of the area is testified by the basaltic rocks of the seaside. Water sources are frequent, rivers from the area including the Rio Mannu. The"

Peloids consist of humus and minerals formed over many years by geological and biological, chemical and physical processes. Numerous peloids are available today, of which the most popular are peat pulps, various medicinal clays, mined in various locations around the world, and a variety of plant substances. Also, health spas often use locally available lake and sea muds and clays. Peloid procedures are also various; the most common of them are ""peloid wraps"", ""peloid baths"", and ""peloid packs"" applied locally to the part of the"
"Pumice Pumice (), called pumicite in its powdered or dust form, is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. It is typically light colored. Scoria is another vesicular volcanic rock that differs from pumice in having larger vesicles, thicker vesicle walls and being dark colored and denser. Pumice is created when super-heated, highly pressurized rock is violently ejected from a volcano. The unusual foamy configuration of pumice happens because of simultaneous rapid cooling and rapid depressurization. The depressurization creates bubbles by lowering the solubility of gases (including water"
"stone used for them were either tuff, or vacuolated or vesicular basalt (basalt with many small holes in it, due to gas bubbles trapped in the cooling lava): both provide a rough surface, appropriate for abrasions and grinding; but tuff was 3 times more used than vesicular basalt, the latter for which there is no clear evidence of production centres on the isl. The use of tuff rather than basalt, had a notable wear-effect on the islanders' dentitions. Tuff is made of consolidation (aggregated and compacted) volcanic ash; it is technically an igneous rock but is more akin to a"

Types of oils that can be used are mineral oil, olive oil, some lotions or commercial preparations in an electric heater. Dip powder manicures are an alternative to traditional acrylic nails and gel polish. Dip powders have become popular due to ease of application. They are similar to traditional silk or fiberglass enhancements, with the fiber being replaced by acrylic powder. Both methods rely on layering cyanoacrylate over the natural nail and encasing either the fiber or acrylic powder. While a single"
"Architectural remains of the Minoan civilization on Crete have shown evidence of the combined use of slaked lime and additions of finely ground potsherds for waterproof renderings in baths, cisterns and aqueducts. Evidence of the deliberate use of volcanic materials such as volcanic ashes or tuffs by the ancient Greeks dates back to at least 500–400 BC, as uncovered at the ancient city of Kameiros, Rhodes. In subsequent centuries the practice spread to the mainland and was eventually adopted and further developed by the Romans. The Romans used volcanic pumices and tuffs found in neighbouring territories, the most famous ones"

It is not recommended to touch Pele's hair, because it is very brittle and very sharp, and small broken pieces can enter the skin. Gloves should be worn while examining it. Pele's tears might occur with Pele's hair. They can tell volcanologists a lot of"

On land, they are very common at plate boundaries and in flood basalt provinces. It has been estimated that volcanic rocks cover about 8% of the Earth's current land surface. Volcanic rocks are usually fine-grained or aphanitic to glass in texture. They often contain clasts of other rocks and phenocrysts. Phenocrysts are crystals that are larger than the matrix and are identifiable with the unaided eye. Rhomb porphyry is an example with large rhomb shaped phenocrysts embedded in a very fine"
