The Lens

Bubbles got into Ryukyu glass because the material was salvaged. Crushed bottles carry air and impurities, and the furnaces of the late 1940s could not drive all of it out. Every piece came out speckled. In the trade that is a defect.

The buyers disagreed. What the craftsmen treated as a failure of the process was the thing that made the glass look like nothing else. By the time Okinawa returned to Japan in 1972, the bubble technique had settled across the industry as the signature of Ryukyu glass.

It is made on purpose now. The bubbles in Cosmo are stars, and their size and spacing are decisions.

Somewhere in that reversal is the character of the whole craft. It did not hide what the material did. It kept it.

How it's made

Bubbles are worked into the melt and then shaped by how the piece is blown. Blow hard and they stretch into lines. Blow gently and they stay round. The pattern is a record of one maker's timing on one morning.

Pairing

Anything clear. Water, sparkling water, cold barley tea. The bubbles are easier to see with nothing in the way.
