You know how you can't put metal in a microwave...well tea bag labels have staples in it, but it doesn't cause a spark or anything in the microwave. Why is that?

They are so small they rarely have any effect. Although I have heard of a tea bag burning up that floated. They recommend that to keep the ends of the legs of a turkey from getting overdone in a microwave to put little pieces of aluminum foil on the tips. It directs the waves away by reflection. I have seen the results if corel ware with the metal in the cup handles is put in, it sparks.

They're way too small to have any significant currents set up in them by the microwaves. The wavelength in a microwave is about .15 m and for any current to be set up in a metal object, the size of the object needs to be a significant fraction of the wavelength. The staples are too tiny.

certain metals arent bad I suppose since lately I've seen more and more microwavable containers with it on them-I think as long as its not shiny and its small its okay
