How far apart should my containers be while the candles cool?Space your containers about one half inch apart so that air may flow between them. Containers too close together can cause slow uneven cooling, resulting in a poor candle surface quality and frosting.
Should I wash my containers prior to creating candles?Washing or dry wiping is unnecessary and not recommended unless your container is dirty.
What is a proper burn pool for a container candle?As a general rule, try to achieve a full burn pool of 1/4 to 1/2 inch deep, from side to side in about the same number of hours as the number of inches the diameter of the container. For example: An Apothecary jar with a diameter of 4 inches should achieve a burn pool depth of 1/4 to 1/2 inch, side to side, within about 4 to 5 hours. Too large of a wick will produce deeper, quicker burn pools but may also cause sooting and short burn times.
