The word "pumice" is spelled using the phonetic transcription /ˈpʌmɪs/. It is a volcanic rock that is formed from the cooling of lava which contains high levels of gas. Its rough surface and ability to float on water make it a popular ingredient in beauty and skin care products. The word originates from the Latin word "pumex". The spelling of this word may be confusing because it looks like it should be pronounced "poo-miss", but the correct pronunciation is "pum-iss".
Pumice is a naturally occurring, lightweight, igneous rock that is formed during volcanic eruptions. It is characterized by a porous and frothy texture, typically light in color ranging from white to gray or light brown. The distinguishing feature of pumice is its high concentration of gas bubbles trapped within its structure.
With a low density and high porosity, pumice floats on water due to the abundance of gas pockets. It has a unique abrasive quality that makes it widely utilized in various industries. Its porosity and abrasive property make it an ideal ingredient in skincare products, such as exfoliating scrubs and foot files. Pumice is also employed in the beauty industry for foot and hand treatments to remove calluses and dead skin cells.
In addition to its cosmetic applications, pumice has several practical uses. Due to its lightweight nature, it is sometimes used in construction as a lightweight aggregate in concrete, providing improved insulation properties and reducing the overall weight of structures. Pumice is also utilized in horticulture as a soil additive to improve drainage and aeration, enhancing the growth of plants.
Due to its volcanic origin, pumice is found in abundance near volcanic zones and is commonly extracted through mining. It is considered a valuable resource due to its wide range of applications in different industries, making it an important component in various products and processes.
A volcanic substance or lava, so light and porous as to float on water, usually of a whitish-grey colour.

The word "pumice" originates from the Latin word "pumex". It is believed to have its roots in the Ancient Greek term "pūmex" (πῦμεξ), which refers to a volcanic rock with a frothy and porous nature. The Greek term, in turn, might have been derived from the Greek verb "πέμπω" (pempō), meaning "to send" or "to throw", reflecting the volcanic ejecting process. It is worth noting that the Latin term "pumex" not only gave rise to "pumice" in English but also to similar words in other Romance languages, such as "pumicite" in French and "pomez" in Spanish.
