Frequently Asked Questions

Q: What is a diatomite coaster and how does it absorb water so quickly?

A: A diatomite coaster is made from diatomaceous earth — a naturally occurring, highly porous material. Its millions of tiny micro-pores instantly draw moisture away from surfaces on contact, making it far more absorbent and faster-drying than fabric, cork, or silicone coasters.

Q: How do I clean and maintain my diatomite coaster?

A: Simply rinse the coaster under running water and allow it to air-dry completely in a ventilated area. Avoid soaking it for extended periods. If the surface becomes less absorbent over time, lightly sand it with fine-grit sandpaper to restore its porosity.

Q: Is this diatomite coaster suitable for bathroom use?

A: Absolutely! Its dampproof, quick-drying, and non-slip properties make it an excellent choice for bathroom vanities, soap dishes, toothbrush holders, and other humid-area applications.

Q: Does the coaster come in different shapes?

A: Yes, the coaster is available in both square and round shapes, each measuring 9 cm × 9 cm (3.54 in × 3.54 in), in a range of neutral tones including Dark Grey, Light Grey, Grey & White, and White.
