First off don't hold me accountable if your microwave sparks. But so far im happy with my results. I bought a piece of galvinized flashing at home Depot. Its black on one side and gray on the other. I melted 2 cups of old remelts in a 2 cup anchor cup. Then cut the cooled plastic in half so i could trace an outline onto my flashing and then cut it with tin snips. I used 5 minute jb weld clear epoxy, to glue the flashing to the cup,but added a couple drops of black plastisol colorant to hide and flashy metal. Heres the result and no sparks in the micro. It makes more of a swirl than a laminate but I think cooler plastic might work better. Good luck
