Beehive shelf : ウィキペディア英語版 | Beehive shelf
A beehive shelf is a piece of laboratory equipment, usually of pottery, used to support a receiving jar or tube while a gas is being collected over water with a pneumatic trough. ==History==
The name derives from the design of early beehives made from bound grass called a skep.The squat circular shape was made by binding the grass bundles to form a flat wheel. Sides were added using the same material with a cutout to allow honey bees to enter and leave the hive.
