A heat gun is a great tool for candle makers. It can help fix flaws such as air bubbles, wet spots, and small sinkholes. Turn the heat gun on low and hold it fairly close to the container where there is a flaw. Allow the wax to melt slightly which will often fix any imperfections in the wax. You can also use a heat gun for warming a container before adding melted wax. Heat guns can be purchased at a hardware or home improvement store such as Lowes or Home Depot.
