People have probably been using beeswax for as long as they have been collecting honey from beehives, which is as long as there have been people alive. In the ancient world, where there was no plastic or any other kind of petroleum or rubber, people used beeswax for all kinds of things.
Ancient doctors also used beeswax in medicine – to fill cavities in teeth.
Artists mixed beeswax with colors to make paint, and they painted with this wax on wooden tablets. Coating wooden tablets with wax also made a very common writing surface for temporary records, much cheaper than papyrus or parchment.
In the Middle Ages, when more people lived further north, they found olive oil was too expensive to use for light. Olive trees didn’t grow well in northern Europe. So people started to use beeswax to make candles for light.
