A heat gun is a great tool for candle makers. It can help fix flaws such as [rough, uneven surfaces,](https://www.candlescience.com/wax/soy-wax-trouble-shooting-guide/#roughtops) [cracks](https://www.candlescience.com/wax/soy-wax-trouble-shooting-guide/#cracking), and small [sinkholes](https://www.candlescience.com/wax/soy-wax-trouble-shooting-guide/#sinkhole). Turn the heat gun on low and hold it fairly close to the candle where there is a flaw. Allow the wax to melt slightly and this will often fix any imperfections in the wax. You can also use a heat gun to carefully warming a container before adding melted wax. Heat guns can be purchased at most hardware or home improvement store, and smaller versions can often be found at craft stores near the shrink-wrap materials.
