Glass Floats on the Shikotan island, Russia
Here is an old picture (unfortunately there is no date of when it was taken available) from the fishing port in Shikotan, Russia.
As far as we know, Russians are still using and manufacturing glass fishing floats in the East of Russia, although glass floats are considered by fishermen as ‘unpractical’ and ‘fragile’, so they mostly use plastic and aluminium floats now.
