There is another development called Advanced Beekeeping that will enable the production of wax from your apiaries in Manor Lords. This is making some players think there is a way to craft candles. Sadly, there is no crafting system in place for candles yet.

Right now, there is no way to do anything with the wax except sell it for some profit. It seems obvious that we will see more crafting available in the future. Considering that Manor Lords is still in early access, we can assume that as Slavic Magic adds new content, we will see candles play a part in our profit-making schemes.
