I used Visionware (specifically, the 2-1/2 qt. saucepan) on open coil and solid
surface electrics for over 15 years, and never had a problem.

But the manuals for both generations of my GE glass cooktops advised:

"Glass-ceramic: Usable, but not recommended. Poor performance. May scratch
surface."

so I gave the Visionware away.
