this is what happened to me. after testing a candle i was making for awhile. a friend ask if i would give them one. i so i did. they lit it at 2:00 pm that afternoon and forgot it was lit and left it on the counter all night lit the next moring they saw it and it was still burning and was ok . when they told me about it i almost fainted.. and the first thing that came into mind was i'am sure glad i had tested it well. or there house may have burned down.( so remember to test test and test again)....Dan
