Ive used cast iron skillets regularly on my ceramic-top electric stove for 12 years now. One isn't even flat!
They work just fine. They won't crack the glass unless you drop them. But then you could drop an Emerilware lid on it and crack it.
The manufacturers are on the hook for replacement during the warranty period, so they tell you not to use heavy cookware, thinking it's most likely to be dragged (and scratch) or drop.
There isn't any functional reason why you can't use it.
Check out the Cookware and More website for great deals on AllClad. Also Williams Sonoma outlet stores often nearly give away Emerilware.
