英文說明:When fishing with a net, the fishermen wanted to avoid having the net sink to the bottom. Because the nets were weighted, when they are cast, floats were attached to the upper edges. These floats were made of ceramic or glass. If glass balls were used, several were tied together to increase buoyancy. The glass floats came in various sizes, with the smaller ones being about the size of a fist. The appropriate size was selected based on the net being used. This glass float is complete although its net is damaged.
