s of fatty acids and various long chain alcohols. Typically, for a honey bee keeper, 10 pounds of honey yields 1 pound of wax.

Production

The wax is formed by worker bees (the females), who secrete it from eight wax-producing mirror glands on the inner sides of the sternites (the ventral

The new wax scales are initially glass-clear and colorless (see illustration), becoming opaque after mastication by the worker bee. The wax of honeycomb is nearly white, but becomes progressively more yellow or brown by incorporation of pollen

 are stored. For the wax-making bees to secrete wax, the ambient temperature in the hive has to be 33 to 36 °C (91.4 to 96.8 F). To produce their wax, bees must consume about eight times as much honey by mass. It is estimated that bees fly 150,000 miles, roughly six times around the earth, to yield one pound of beeswax (530,000 km/kg).

Processing

When beekeepers extract the honey, they cut off the wax caps from each honeycomb cell with an uncapping knife or machine. Its color varies from nearly white to brownish, but most often a shade of yellow, depending on purity and the type of flowers gathered by the bees. Wax from the brood comb
