Make sure to change those paper towels after each batch because the potatoes from the next batch will stick. The time will vary how long will take for your potatoes to get into chip form. Test one batch and see what is the best that comes out of your microwave. Make some space between potato slices when you are lining them up on the plate before microwaving. The plate will be HOT, be careful how you are handling it. Take the plate out of the microwave with oven mitts or kitchen towel. If you are concerned about microwaves or don't use them at all, clearly this is not for you. Read this article on PaleoLeap about microwave hazards.
