Pumice is a natural lava-based substance that is expelled from volcanoes. When a volcano erupts, the lava it spews out is very hot, and it rapidly cools when it is exposed to the cooler air outside. This rapid cooling transforms the foamy lava into pumice. Its glassy finish and abrasive texture given it a number of household and construction-based uses.
There are a number of reasons that pumice has found popular use as a consumer material. As volcanic activity happens globally, it is naturally produced in many countries. It often doesn't require extensive processing, so it can be a cost-effective alternative to other products. It also offers a number of unique qualities that are valued by different industries.
One of the main qualities of pumice is that it is abrasive. This abrasiveness makes it valuable in applications that require a scrubbing substance. For example, some natural household cleaners have been developed that use pumice to help scour stains from appliances. Other products use it as a way of cleaning and scrubbing skin from the body, such as from the bottom of the feet. Additionally, as pumice is a naturally-occurring substance, using it instead of more chemically-based cleaners can have environmental benefits as well.
Winner will receive block in picture. I use it as a plant base for my cactus and succulents, it breaks very easily with a garden spade or a hammer (claw side). I can email the winner several uses for it.
