Burners and hot air guns are big helpers when it comes to, for example, working with crystal resin that sometimes tends to create unwanted bubbles inside jewellery pieces. These can be removed using a burner or a hot air gun with which you can slide over the jewellery and let the hot air release the bubbles. Besides that, you can also use a hot air gun or a burner for soldering, joining plastic components or soft metals or if you want to take a coating off something. Burners are also practical tools for working with Art Clay. Gas burners can be easily re-filled with propane butane.
