Beeswax is a natural wax made by honey bees. Worker bees produce the wax using glands on their abdomens. They use the wax in their hives to produce a hexagonal matrix of cells within which to store honey, store pollen, and raise brood.
When we harvest honey, the wax cell cuppings are cut off from the honey frames. The frames are returned to the hives for the bees to use again. But the cuppings remain, and are melted down and rendered into beeswax.
Beeswax has been used throughout history for things such as waterproofing and primitive metal casting techniques. Today, some of the most common uses are beeswax candles, all natural lubricant such as for fixing squeaky drawers, and natural skin care products.
