1. For the first light, make sure you leave it lit for a minimum 2 hours or until th wax has melted all the way across. This is to ensure the candle won't tunnel. (Tunneling will grow deep like a crater and you don't want that if you want a long lasting candle)
2. Make sure you trim your wick before every use. Start by trimming the wick to between 1/8 and 1/4 inches long. You can use scissors, nail clippers, or a specialised wick trimmer. Why you ask? Trimmed wicks will give you a cleaner, brighter burn. Untrimmed wicks are a lot more likely to take on a weird mushroom-esque shape that dulls and obscures the flame.
