It's a HEAVY pan and I've been pleased with how it's performed but I took it out this morning to saute some apples for a dessert I'm making and it seems to have warped! I use it on a ceramic cooktop...I never cook above med/med high(#6 setting of 10) and haven't had a problem with any of my other cookware warping. I'm really surprised. I'll take it back under warranty. Warping shouldn't be a regular occurence with a properly made copper pan right? I was thinking about investing in a couple more pieces of copper(though was already thinking about a thicker layer of copper)but if I have to worry a lot about warping maybe not. Sat Jan 13 17:26:19 -0800 2007 16406 ziggylu 1 2185262 Did you stick it under water while it was very hot? If not, no, it shouldn't warp and at a presumably heft price, I'd certainly look into returning it. I wouldn't bother with an even exchange, it doesn't bode well for that line in general, I think. Now, I notice you mention "layer" of copper, so I'm confused about what you have. "Copper pans" are solid copper with a thin layer of something less reactive covering it. What you may have is a SS pan with a thin copper plating or something, in which case that's a whole 'nother ball of wax. Exacatly what brand/line are we talking about?

(It's not a layer, it's the pan's base material.) Mauviel should not warp, but I have no idea what if anything they have to say about using it on a ceramic range. At a minimum, call Sur La Table and ask them. I'd lean heavily toward returning it, myself. Sat Jan 13 17:54:25 -0800 2007 2185184 11980 MikeG 1 2185282 It's co-branded Sur La Table and Mauviel. I'm not sure they carry this particular line anymore(it has a brass handle) though the still do have some Mauviel. It's either 1.5 or 1.8mm copper with a stainless steel lining. I've read that 2+ mm is better. My husband does the dishwashing. I'll have to ask him about having washed it hot. edit: the pan I have is basically this one with a Sur La Table branding as well. http://www.metrokitchen.com/item/M-6526-30/ I will return it for sure...and am glad to hear this shouldn't be a typical concern with a copper pan. Did really like how it performed like I said.

Sun Jan 14 15:07:02 -0800 2007 2185184 16537 andreas 1 2189619 You are probably talking about Mauviel "table top" it's really made more for nice table presentation. I use the 2.5 Mil Mauviel daily and have not had a problem. I abuse it regularly on my hi power gas burner and then put water in while hot to clean it. I have never had any kind of issue with it. Now that being said I have switched to Faulk Culinar, because of it's ease of maintenace (www.copperpans.com) They actually own the patent on the ss bonding that Mauviel useses. Mon Jan 15 05:19:03 -0800 2007 2185184 23935 irodguy 1 2192199 The Sur la Table line is exactly for that -- serving. It's not thick enough to cook in. The 2 mm. Mauviel is barely thick enough, and the 2.5 mm. is much better. The 2 mm. has a rolled lip at the top and thin brass handles. The 2.5 mm. top is straight with heavy cast iron handles. The 2.5 mm. ware is **really** heavy, but it cooks like nothing else. Tue Jan 16 00:01:38 -0800 2007 2185184 10539 KRS
