CANDLE TIPS (A SERIES) #2
Have you noticed that your candle is tunneling? Is the wax along the edges not melting?
Wax has a memory. Every time you light your candle ESPECIALLY on the first burn... you should leave it burning long enough for the entire surface to melt. If you do not do this the melted wax will continue to stop at the same spot it melted to last time.
HOW DO I FIX THIS?
Continue to burn your candle. Every time you light it make sure that you are letting it burn for a full 4 hours!! If too much damage has not been done, it should even out after a few burns.
