These have held a fascination for me for years. My Grandmother had a couple of these (without the netting)
They always looked so pretty hanging by the windows. Over the years I have managed to pick up a couple of them for myself. I found a few that actually have the netting still on them.
They were once used by fishermen in many parts of the world to keep their nets afloat. Norway was the first country to start production and use of glass fishing floats around 1840.
By then, glass had replaced wood or cork throughout much of Europe, Russia, North American, and Japan.
The earliest floats, including most Japanese glass fishing floats, were handmade by a glassblower.
These glass floats are no longer being used by fishermen, but many of them are still afloat in the world's oceans.
I think it is fascinating that there are many of these are still out floating around. They can even be found washed up on beaches.
The most common colors were the blues and greens, however clear, amber and amethyst ones were also made. The most highly sought after and rare ones are cranberry or red colored floats.
Most of the colored floats available today are replicas, but still fun to have.
This one has the makers mark on it.

Here is a modern hand blown set;
So if you happen to go walking along the beach, keep your eyes open, you never know what you may find.
