How to make a simple Silicone Mold Part 1

Would this be the best sort of mold to make crayons? I want to poor the mold over an action figure, cut it open, take out the action figure and poor the crayon wax into the mold. Good or no?

@friskedkitty Silicone RTV can withstand about 250 degrees F and Platinum Silicone can handle up to 500 degrees F. As long as the crayon wax melts below those temperatures, you should be fine.
