Much that we want to make it burn for a long time, wax should only burn for four hours. It is important that after this time of burning, it should be doused. Let it cool for a couple of hours and trim it before lighting it again. In trimming the wick, it is important to observe the half-inch rule. According to this rule, it is recommended not to use the candle if the wax of the candle is only half an inch at the base of its container.
This rule will eliminate potential damage on the surface or the counter of the container caused by the heat. The container, especially if it is made of glass, could become hot on the bottom part as the flame reaches the base while the most part of the wax is slowly being expended. It is also important to burn the candles away from anything flammable, drafts, or other sources of heat. Ensure that burning wax are unreached by pets or children.
