Hey, you cant go and answer something from way up there. By the time I went back to see what the question was again, and got back down here, I had to go back up and read it a second time.
I think a thick pan WILL pick up and hold more heat than a thin one, but the key here (I think) is continuous usable heat. Thick pan can pick up, hold, and discharge more of that high heat for longer.
Of course, setting food directly onto the heat source and skipping the pan works out great too.
For a good example, put some tin foil in the oven. Take it out with your bare hands. After a second or so, its not hot anymore to the touch. Try that with a sheet pan. Or better still, DONT! It'll stay hot in your hand for a lot longer. You can even touch foil while its in the oven in contact with hot food and its not going to burn you. All it can do is conduct, its not able to store that much heat on its own.
Similar with a pan...stick a steak in a thick heavy pan, and the pans thermal absorption ability can take a lot more discharge to the meat before cooling off, in the meanwhile the heat source can recharge it. Thin pan loses its heat almost immediately and then you've got a cool spot in the pan until the heat source gets it AND the food thats sitting on it back up to temp.
Given that it might have taken 5-10 minutes to get the pan up to its original temp, the thermal recharge situation becomes evident.
I received my first lot of four 12" pans the day before yesterday. Bad packaging. They just threw the pan into a large flat box, tossed in a twisted up length of brown paper and taped it up. Pan was probably banging around in there pretty good, but no broken stuff. On looking at one-star amazon reviews, seems they ship them all this way and some of them arrive busted. Stupid.
I did a little additional seasoning in the oven and then upside down on the grill. Just made chicken-sundried tomato sausages and scrambled eggs in it and its as nonstick as teflon pans. Beautiful.
Pan looks identical to the ones pictured above.
Very pleased with my $7.50 pans...now i'm just waiting for the $6 8" ones...
