i keep several lenses from arc welding hoods around the kiln.. they are
great to peep through at cone 10, and when you have guests looking in the
kiln for the first time it is nice to shield their eyes. any welding supply
store has a variety of glass lenses in a variety of power. i put a duct
tape rim around mine. and as Kirby Puckett says: "take care of your eyes." mel
