Tealight candles
Tealight candles are very miniature options. They are encased within a thin metal cover. This results in the wax becoming completely liquefied while it is lit. They have a wide range of applications.
For instance, tealight candles may be used as nightlights. This is because they are very long-lasting. However, some people distinguish these designs from larger nightlight candles as the larger options can last for over twice as long.
Tealight candles may also be used as warmers for food and beverages. The name is appropriate because tea is one such thing that they may warm. They are also often used for heating smaller, non-electric fondue pots.
