Enhance Candle Longevity with a Pinch of Salt
Originally Published 2 years ago — by House Digest
Adding a pinch of table salt to melted candle wax can make the candle burn longer by raising the melting point of the wax and keeping it away from the hot flame. Another method involves coating the exterior of a container-less candle with a salt-water mixture, which creates a thin salt coating that helps prolong the burn time. However, it's important to use the correct amount of salt to avoid difficulties in lighting the candle or dimming the flame.
