The stone is sufficiently cemented to be resistant to weathering but not so compact that it can’t be carved and cut by stonemasons.

In fact, the Bath Stone dries so quickly, you can actually watch the wetness evaporate.

What is Diatomite bath mat?

What is a diatomite mat? Diatomite, also known as diatomaceous earth, contains millions of micropores. This allows water to evaporate quickly and prevent the accumulation of moisture and bacteria, making it a highly absorbent and fast drying alternative to traditional bath rugs.

What is diatom mat?

Diatom mud absorbent mat is made of diatomaceous earth as raw material. Diatomaceous earth is a natural mineral. Its main component is silicic acid. It has a special microporous structure.

What is diatom mud?

Diatom mud is porous substance containing additives. Using modern technology, diatom mud is modified into several designs. These designs are, further, used for furnishing purpose and beautification of interiors. Moreover, diatom belongs to the category of fossil.
