Put the candles "accident-free" on the candlestick
Just back when tablecloths had: The candle should be put on the candle holder (expertly, one would say, put on the thorn?) And breaks down promptly apart. Annoying, because you can usually do nothing with the candle then!
However, if you first heat up this thorn with a match or a lighter and then immediately put the candle on it, that can not happen anymore. The heat of the metal thorn literally goes through it "as if through butter."
