I had a really scary incident once: I tend to take left over candle wax, pour into a large 3
wick container and burn for personal use just to use up the wax and scents. Had this container burning in my bedroom one day, went in there and found the entire container on fire...as it turns out, having layered this candle with multiple mixtures, the wicks were burning too hot, soot accumulated on the sides of the jar and that soot eventually caught fire....lesson learned!!
