Here are some tips for best results...
The first burn is the most important because soy candles have a "memory." This means that the candle wax will melt across only as far as the first time it was burned. During the first burn, let your wax pool all the way to the edges of the container. This way you will not create a "tunnel", leaving wax on the edges of the container.
A good pool will give off the best scent throw.
If you wax is collecting on one side of the jar, creating an uneven burn simply adjust your wick back to the center of the vessel or lean it to the side that needs more heat.
Keeping the wick trimmed to 1/4" will ensure the best amount of scent throw and will prevent the candle from burning too hot resulting in the wax burning up too fast.
Cotton wicks will mushroom, this is a natural characteristic of the wick. Snip the mushroom before each burn.
Keep your candle away from drafts, curtains and magazines or anything flammable.
Keep your candles out of reach of children and pets. Always place candles on a level, heat resistant base.
Soy candles produce very little to no soot when burned properly. If you get any black at the rim of your glass simply wipe it away with a damp cloth, this may be a sign that your wick is too long.
Candles shouldn't burn for more than 4 hours at a time.
To prep your candle for the next burn extinguish it by dunking the wick into it's own pool of wax using a wick dipper or pencil.
