People Used These Candle Clocks To Tell The Time And Wake Up Before Electricity
The candle clock. A timeless invention that has been used to measure time – and wake people up – for centuries. And it works in such a simple but cool way.
Candle clocks, also known as candle timers, are devices that use the rate of burning of a candle to determine how much time has passed. A candle clock in its most basic form consists of a candle, a holder, and a marking on the candle or holder that indicates the amount of time that has passed.
A candle clock works on the principle that the rate at which a candle burns is relatively consistent, making it a fairly reliable method of measuring time. A candle clock works by burning a candle at a constant rate and marking the candle or holder at regular intervals, such as every half-inch, to indicate how much time has passed.
Candle clocks date back to ancient China, with the first recorded reference appearing in a Chinese poem written by You Jiangu in 520 CE. They were used to track the passage of time during religious ceremonies there. The candle was lit at the start of the ceremony and allowed to burn until it reached a certain point, after which the ceremony ended. This was a simple, effective method of keeping track of time.
