How do candle by the hours work?
I'm curious about these candles that are designed to burn by the hour. How do they actually function? Is there a specific mechanism that controls their burning rate to ensure they last for the intended duration?
How many hours does a candle last?
I have a candle and I want to know how long it will last. I'm curious about the duration of its burn time, so I'm asking how many hours a candle typically burns for.
