As time went on, candle-making techniques advanced, and people began to explore different materials and methods to create more efficient and longer-lasting candles. One of the earliest methods involved dipping reeds or sticks into melted tallow or beeswax repeatedly to make candles. The Roman Empire is credited with introducing the wicked candle, which involved dipping a papyrus wick into molten tallow or beeswax. The wick would then be repeatedly dipped into the wax until the desired thickness was achieved. These techniques were simple but effective, and they allowed people to create candles with a more consistent shape and size than before.
