The "diatomaceous earth coaster " is attracting attention as it absorbs the dew condensation on the glass. I've introduced it to Enuchi before, and it was impressive that it dries as soon as it is sprinkled with water. I found such a convenient item at the 300 yen shop "3COINS". I bought it right away.
Diatomaceous earth is a fossilized deposit of diatom shells (phytoplankton, algae, etc.). It has fine holes on the surface and has high moisture absorption and desorption. In addition to coasters and bath mats, it is also used as a material for shichirin and bricks.
The 3COINS diatomaceous earth coaster I purchased this time is a square of about 9 cm x 9 cm and a circle with a diameter of 9 cm. Each has a thickness of about 0.9 cm. Simple and gentle colors will fit into any cup! However, since it is not coated, it seems better to avoid using it on desks and tables with delicate surfaces.
Then, as a test, try spraying water over the whole ...
The color on the front side changed, but the back side was dry and dry. As expected, diatomaceous earth is absorbed properly! Then, when I pour plenty of water in the cup this time ...
When I sprinkled about 2 tablespoons of water, it became moist and moist to the back side, but it did not drip. With this performance, it seems that even if there is a lot of condensation on the glass or cup, it can be absorbed without problems. Although it has excellent moisture absorption and desorption properties, it seems that mold may occur. It is recommended to dry in the shade once a week in the summer and once a week in the winter.
It's a time when you have more opportunities to drink cold drinks with plenty of ice. If you are worried about condensation dripping on the table, why not give it a try? Of course, the price is 300 yen (excluding tax).
