I have been woodworking for twenty years and have been told many, many times to never use silicone spray in a wood shop as the silicone will interfere with some finishes. I have seen pictures of what it will do, so I never use spray silicone in my shop! I prefer to use clear packing tape on top of the pattern. If it is thicker wood like 3/4" Oak or maple, I will also apply clear packing tape to the bottom. If I do that, I will apply a blank sheet of paper first then the clear tape. The tape and the pattern will come off easily with a heat gun or a spray of mineral spirits. Using this method, I never have any burning.
A lot of folks use blue painters tape on top of the wood instead of the clear tape on the pattern. I have a hard time removing the remnants of the blue tape around very small cut outs, so I prefer not to use it.
