Today, people often discover alternatives or substitutes for a lot of things, such as cleaning, hygienic, and industrial products. We already know that baking soda can be used for almost anything, from cleaning to deodorizing. But now, we have another item that can be used as an alternative or substitute for various things, which is pumice powder.

Pumice powder is made from pumice. Pumice, which is also called pumicite in its dust or powdered form, is a volcanic rock that consists of highly-vesicular, rough-textured volcanic glass, which may or may not contain crystals. Pumice is naturally light colored, ranging from white, cream, blue or gray to black.

Pumice is ordinarily produced by explosive eruptions and commonly forms zones in upper parts of silicic lavas. It has an average porosity of 90% and because of its porous nature, it is incredibly lightweight. It is also considered a glass since it has no crystal structure.

Now, if you are to ask how to use pumice powder, then I can give you a lot of answers. And those answers can actually vary from industrial use, for filtration, as a chemical carrier, hygienic or cleaning to horticulture use.

Pumice has several characteristics that combine to make it valuable and versatile. As mentioned earlier, pumice is usually amorphous and generally inert, has a neutral pH, and yet is hard enough to be used as an abrasive. And so, almost certainly because of these characteristics that pumice powder is so useful. In addition, pumice is indispensable because of its sustainability and abundance.

And now, let’s discuss in detail how to use pumice powder in different ways. Grouped based on attributes, the following is a breakdown of where and how to use pumice powder.

First off, let’s discuss how to use pumice powder as an industrial abrasive. Pumice powder is used to polish glass, clean and texturize electronic circuit boards, clean lithographic plates, and buff leather and fine furniture woods.

Second, let’s discuss how to use pumice powder as a product abrasive. Pumice powder has a mild abrasive quality, a benign chemical nature, and an ability to be refined to dust, which makes it an ideal additive for cleaning, polishing, and exfoliating products. And so, pumice powder is used in dental prophy pastes, cosmetic scrubs and exfoliants, hand cleansers, rubbing compounds, scouring pastes and powders, pencil erasers, callous removal stones, and stain removal stones.

Third, let’s discuss how to use pumice powder in manufacturing and finishing processes. As a mold release agent, pumice powder is dusted inside a mold to prevent the plastic or rubber-molded material from binding and sticking to the inside of the mold wall. When used as a textile softening, also known as stone-washing, pumice powder mixed with stiff fabrics or assembled clothing, such as denim, to soften the feel and age the appearance.

Fourth, let’s discuss how to use pumice powder for filtration. Pumice is a practical substitute for sand and anthracite as a filtration and clarification media. It is used in wastewater treatment, drinking water, pumice soil, reverse osmosis processes, biomass support for aerobic treatment process, sludge de-watering, and for beverages.

Fifth, let’s discuss how to use pumice powder as a chemical carrier. Because of the characteristics of pumice, pumice powder is used in agricultural application. Not only can the beneficial chemical be delivered directly to the soil, the pumice stays behind to improve the health and growing capacity of the soil.

Sixth, let’s discuss how to use pumice powder for absorbent and spill containment. Because of pumice’s absorbency, it is used to absorb and hold oil and impurities. And so, it’s useful as a petroleum and chemical dry absorbent. Ingeniously, it can also be used as a kitty litter.

Lastly, we can use pumice powder for horticulture. Since pumice is renowned for its ability to condition soils and growing mediums, it is generally used as a soil conditioner for potting and garden soils, lawn and turf management, landscaping mulches, roof gardens, packing and storage mediums, propagation mediums, growing medium for hydroponic applications, and as seed coatings.
