Regarding Visionware http://www.millscentral.com/visionware1liter.jpg

I have used these on hobs and coils and on my glass cooktop.
I'm wondering if glass on cooktops do not have a tendency to scratch more
than metal pans used on glasstops. Why would that be? I don't know.

At any rate, I don't use the Visionware any longer. I did save them for use
in the microwave, but as I no longer use the microwave, they have been put
waaaaaaaay back on the shelves.

I did use the Visionware without anything between the heat and the pan on
the glass cooktop.

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.
