This beautiful old 12" Japanese glass float has a sort after FF makers mark, plus some trapped water!
This happens when a float is pulled so far under water that the pressure opens up small imperfections in the glass. Water seeps in, but when the float returns to the surface the imperfections close and the water is trapped inside!
Acquired from a local collector it still has it's heavy traditional rope work and is quite a find!
It would look great displayed on the deck, or hanging to catch the light.
Measures approx: 30cm diameter
