That's what she had and it got ruined. A whistle does no good if you forget
what you are doing and leave the house. We had the same thing happen when I
was a kid. We left for church and someone had put the kettle on. Came home
to a house full of smoke and when my dad tried to pick up the kettle, the
bottom was stuck to the burner. Amazingly, once it cooled, the bottom could
be lifted off and the burner was fine. But we had no more tea kettle.
