 What does the blowtorch do for Art Resin? In short, a blowtorch ensures your best chance at getting rid of all bubbles. When you use resin, there is a chance that bubbles will occur. You can take care of these in a number of different ways. Some people have tried using a hairdryer that's really not going to cut it. You can use a heat gun. You can also use a flame of some sort. If you have a big piece, you'd be using a blowtorch for smaller pieces and just for ease of use. I like to use the little kitchen torch for torching creme brulee. When you use a flame, it just ensures that all the bubbles that are in the piece rise to the surface and eliminate themselves. There are other ways of eliminating bubbles. You can blow with a straw or you can poke with a little pin. And a lot of them will just release on their own. But if you want pro results, then a flame is your best bet.
