Terra Cotta pots are effective at conducting heat
Being freezing cold is one of the most dangerous threats to survival. If your heat ever goes out and there’s an urgent need to warm up a room or a campsite, perhaps this trick will help. Simply create a makeshift heater with candles and terra cotta pots.
This earthenware material is an exceptional heat conductor. Light a candle and put a pot on top of it. It is essential for the vase to have holes so that oxygen can get in and the flame does not get extinguished.
