Diatomaceous Earth Coasters – Super-Absorbent, Heat-Resistant & Stylish
Protect your furniture in style with these natural diatomaceous earth coasters.

Frequently Asked Questions
Q: How do diatomaceous earth coasters absorb so much liquid?
A: Diatomaceous earth is a naturally porous mineral formed from fossilized algae. Its microscopic channels draw in moisture rapidly and release it back into the air as the coaster dries — absorbing up to 2–4 times its volume in water without becoming waterlogged.
Q: How do I clean and refresh my diatomite coasters?
A: Rinse lightly under running water and allow to air dry fully. If absorption seems reduced over time, gently sand the surface with the included sandpaper to open the pores and restore full absorbency. Avoid prolonged soaking or dishwasher use.
Q: Are these coasters safe for hot mugs and cups?
A: Yes! These coasters are heat-resistant and can handle hot mugs, teapots, and coffee cups without warping, cracking, or discoloring — making them ideal for all types of beverages.
Q: Do the coasters slide around on smooth surfaces?
A: No. Each coaster features four silicone non-slip pads on the base that grip firmly to wood, glass, tile, and most smooth surfaces, keeping the coaster stable and protecting your furniture from scratches.
