A great way to extend the life of a candle is by putting it in the freezer for a day right before you use it. Keeping the wax cool will make it burn slowly. When you're done burning the candle and you're left with a waxy mess on your candleholder, pop the holder in the freezer for about an hour, then you can chip the wax right off.
Candles will last a lot longer if placed in the freezer for at least 3 hours prior to burning.
Put your candles in the freezer before using them, they'll last longer.
To make your candles burn longer, simply place them in the freezer for a few hours before you use them. This means there will be less dripping too.
