I have had a set of Member's Mark which may be the same as the Kirkland brand triply for over ten years. I learned to cook the Rouxbe way on them on my glass top.

They are a good quality set. I just cleaned the backs for the first time the other day by spraying the backs with oven cleaner then putting them into a plastic bag for the cleaner to do it's magic. It did, no scrubbing required. They look sparkling new after all these years. It's an amazing set for the price.

My only problem was with the largest fry pan (and anyone thinking of buying a glass top should pay attention to this). It warped...the skillet and not the glass top. Warping is a common problem with large fry pans in even the most expensive fry pans.

This was a problem on my old flat glass stove top as my food would burn in the middle of the pan and still be uncooked around the edges. That drove me more crazy than any scratches on my glass top. The smaller fry pans have never warped.

Your glass will eventually get hair line scratches everywhere no matter what you use. They didn’t mention that to me when they sold it to me.
Forget about worrying about the glass top, you can still make it look good using the cleaners they recommend. My glass top was about ten years old and looked pretty darn good all said and done and it took a lot of abuse.

You have to jiggle your pans, so just get used to the idea it's going to get tiny hairline scratches. But like I said, that cleaner brings it back good enough to make it look shiny and new depending on the angle of the light.
I ended up going to Ross and getting a fairly good quality Kuhn Rikon large fry pan with the thick flat plate on the bottom. Cost $30.00. It was well worth it because it would not "spin around in circles" when I was frying and making sauces on that glass top.

In the beginning I thought I needed high quality pans to get the food to come out perfect. I didn't, I just needed to learn to be a high quality cook, the pans didn't have much to do with it. But you do need a skillet that will remain FLAT especially on a glass top.

Also, what about your cast iron skillets? You've gotta have at least one fry pan if you want to produce amazing food. I used that and a cast iron griddle on my glass top. After a while, I was pretty brutal with those pans on my glass top.

Still, my glass top took the abuse and looked great after all those years when I used that cleaner it recommends (which I rarely did). Yes it had the hair line scratches everywhere if you looked close enough.
Frankly, I'd never own a glass top again. I can't imagine what the designers were thinking. Your stove top takes the most abuse in the kitchen. If you have to worry about that, and/or accidentally breaking the glass with a heavy cast iron pot that slipped through your hands, AND not burning your food while you are worrying about all this, it can make cooking a miserable experience. It did for me anyway until...

I say, like anything in life you are worried about getting scratched, even a new car, go a head and scratch it somewhere on purpose. It takes a lot of pressure off all the worry that goes into not getting it scratched.

As an example my new shiny pick up truck was the largest vehicle I'd ever driven. It was sweet, not a scratch on it. I proudly drove my truck everywhere and parked it in the "south forty" (farmer's term) well away from any other cars so as not to get it scratched.

Then one day (about two weeks after I bought it), I had to back it out of a friend's driveway. No big deal right? Well, if your truck bed is higher than say... a mail box, it becomes a big deal when you take that mail box out and put an amazingly small dent into your tail gate in the process.

I took two mail boxes out before I learned how not to do that. But at least the worry was off and I didn't have to hike a half mile across a parking lot to get inside a store during the daily summer South Florida torrential down pours.

So by the time my husband put a two foot long deep scratch on the side of the truck (a week later) while putting in a bicycle, I didn't mind so much.

But that's me, my head is already filled with way too much stuff I worry about in life than to add a glass stove top to the list.

In the beginning I was extremely cautious with my stove. I assisted my pots and pans in "tip-toeing" around that stove for the longest time until I had something thick and sticky boil over....I wondered how the heck are you not going to NOT scratch that stove getting that burned on goo off? I tried everything before giving up and using the fine grade steel wool which was the only thing that could get it off.

That's when I realized I needed to let that worry go. My husband was the only one who had the patience to clean that stove top.

You will have pots boil over, it's just a part of life. So some areas where it boiled over, I could never really get to look shiny and new again. Maybe there is a way to get it shiny again, but I had more important things to do with my time.

After a while I deeply missed my old rickety burners and all the abuse I was able to administer and still get it to look new with way less effort than required by a glass top.

I ended up with a gas stove by default. It came with the new house we bought. So I got really lucky. If it had come with a glass top, I would have ditched it before we moved in and replaced it with the old burner style.

But again, that's just me and I have the patience of a gnat.

Frankly, we passed up some amazingly beautiful houses because they didn't have gas stoves. I could be living in a MUCH more beautiful and amazing house than the one we bought, just because of there not being a gas line running to the house.

I admire those people who have the patience to produce amazing food on a glass top and never put a scratch on it. I have no idea how to do that.

In conclusion, even though I'd never own one again, it's probably more my personality that's the problem and not the stove. After years of abuse, that glass top still looked amazingly good when my husband couldn't stand looking at it anymore and cleaned it properly.

I hope this helps. I did sorta ramble on. I've been really chatty lately. I comes in cycles.

Best wishes to all.

I love you Rouxbe!!

I've been purchasing wedding gifts at cooking.com for prices better than in any stores, no tax and usually no shipping. Sign up to get their emails and you'll get all kinds of bargains.

As mentioned previously, the Kirkland branded set has given me absolutely no buyers remorse. I use it daily and still marvel at the quality for the price. That and a full set of well seasoned cast iron in my kitchen leave me wanting nothing (at least in that arena)
