I hate to burst your bubble. I am a professional glass artist. What you want to do cannot be done with tools the woodworker will have. It has to be sandblasted by someone who knows what they are doing. DO NOT use the scroll saw. That is very dangerous. It will shatter and possibly explode from the friction. Glass is NOT cut it is scored or ground down with a special water cooled saw called a Ring Saw. Taurus Ring Saw if you want to google it. Phone a glass company and see what they have at hand or call a stained glass store and see if they will do it with a ring saw. Mirror is very fragile and thin. Especially if you are using mirror tiles. Call a pro!
