Globe of Water

Tamagami Washi Wallpaper series boasts the beading technology to repel water and dirt. This finish uses Silicon (Si), (not to be confused with Silicone) is the second most abundant element in the earth's crust, commonly used in glass, concrete and ceramics. This finish creates fine hair on the paper's surface, similar to fuzz on leaves, or feathers of a bird. Water beads up by surface tension, just like droplets on a lily pad. However, unlike vinyl wallpaper, the washi remains breathable and doesn't trap moisture underneath.

The second photo to the left is a droplet on washi also but without Silicon finish. As soon as water touches the paper, it starts to soak in. Reflections are no longer in a circle, the droplet is losing its globe shape.

Tama is the Japanese word for a globe. A drop of water on tamagami can remain in a perfect shape of globe. See the series of white squares in the photo above, how they make almost complete circles together. They are reflections of the light from shooting this micrograph. It shows how close the droplet is to a perfect globe. And amazingly, it's all about surface tension.
