“Glass floats, glass fishing floats, or Japanese glass fishing floats are popular collectors’ items. They were once used by fishermen in many parts of the world to keep their fishing nets, as well as longlines or droplines afloat.

Norway was the first country to start production and use of glass fishing floats around 1840, many of which can still be found in local boathouses. Christopher Faye, a Norwegian merchant from Bergen, is credited for their invention. The glass float was developed through cooperation with one of the owners of the Hadeland Glassverk in Norway, Chr. Berg.

The first time these “modern” glass fishing floats are mentioned is in the production registry for Hadelands Glassverk in 1842. The registry shows that this is a new type of production.

The earliest evidence of glass floats being used by fishermen comes from Norway in 1844 where glass floats were on gill nets in the great cod fisheries in Lofoten. By the 1940s, glass had replaced wood or cork throughout much of Europe, Russia, North American, and Japan. Japan started using the glass floats as early as 1910. Today, most of the remaining glass floats originated in Japan because it had a large deep sea fishing industry which made extensive use of the floats; some made by Taiwan, Korea and China. In Japanese, the floats are variably known as ukidama (浮き玉?, buoy balls) or bindama (ビン玉?, glass balls).

Glass floats have since been replaced by aluminum, plastic, or Styrofoam.”  Source:

  1. I can imagine the most unscrupulous fishermen smashing the glass floats to sink the nets of their competitors. Has that ever happened?

  2. Glass floats. Very interesting. Wonder how often they shattered to pieces. Lovely shot of you and the son. Looks like you are crouching snapping the shot 😀

        • You can buy them in souvenir shops. I have one of these glass floats at home, complete with woven threads. I think the price was around 10 Aussie dollar, so about the same price as a McDonalds meal in Australia. The Wiki article says that “The most prized and rare color is a red or cranberry hue. These were expensive to make because gold was used to produce the color.”
          I checked Ebay for you and the prices range from 5 US $ to 349 US $, but they I’m guessing that they’re all reproductions and that the 349$ one is just a scam.

    • Yes, that’s my son you can see. More photos of these magic crystal balls coming up soon (just have to finish the editing of all the shots I took up North first, but I’m nearly there).
