While I was cooped up at home, I was looking for something interesting to photograph, and I found a pottery vessel that I bought in Okinawa a long time ago. It is a beautiful vessel with a shining metallic blue interior.

Pottery is colored by the complex chemical reactions of the glaze during firing.

I have no expertise in pottery, having only touched it in a pottery class, but since I work in chemistry, I find it interesting from both the artistic and chemical aspects.

The glaze flowing over the bottom of the vessel creates intricate patterns that look like lava. The radiating patterns in some places suggest that something is crystallizing. The metallic glow is mixed with blue areas. Cobalt (Co) is a typical blue color.

This image was taken with a DX D500 + macro lens and an old 2x telecon.

It looks like an aerial photograph of some island. The random shapes that occur at the bottom of the vessel are somewhat similar to global topography, and remind me of fractals.

Since it is metallic, the impression changes considerably depending on how the light hits it.

One of the bowl seemed to have a Jupiter-like atmosphere, so I took a picture of it like that.

Part of a coffee cup saucer. Fine crazing (cracks in the vitreous of the glaze) is spread out like a map. The bluish area appears to be bubbling and looks like a splash.

A fireball-like pattern appears on the glassy part.
