Great thread, good info here.
My Story:
The War Department wanted a glass-topped electric stove. I had no problem with it. So I was like, "Okay."
Delivered, set up, looked great, War Department is happy, I'm happy when she's happy.
At about 11:00 O'clock that night I woke up with very bad feelings that I cannot cook with my cast iron on the glass top. I'm in a real swivet and climb out of bed, go into the kitchen and start reading the brochures, and looking at the glass top.
I then realize, I CAN'T USE MY CAST IRON ON THIS STOVE!!.
She walks in about midnight asks what I am doing, and I tell her what I just found out to my horror.
She says, "Of course you can't cook on my stove with cast iron." Then goes to bed disgusted of my problem.
