I made a passable, cool-looking new lid after me repeatedly boiling the kettle dry took its' toll on the glass lid. I salvaged the metal ring and knocked out any remaining glass chunks.Then I found a pickle jar lid that was a little smaller than the ring. I carefully pounded with a hammer until it would pop into the ring and not come out again. Poked a hole and put an old knob from the bathroom cabinet on. The original plastic one was melted.
I love crap like this!
