A couple of key candle rules will always be listed here. Please read carefully.
-NEVER leave your candle unattended, no candle is in a "safe space" if it's not being monitored.
-Keep your wicks trimmed, the longer the wick the taller the fire.
-On the first burn, make sure you're letting the wax melt the entire top evenly before extinguishing to prevent candle tunneling. Candles have memories, and won't burn past this mark the next time if you put it out too soon.
-Never burn a candle for longer than 3-4 hours. This creates a lot of hot wax, and a wick that is too long.
