Clearly the larger pan is heavier than the much smaller crepe pan, but not only because of the sheer size difference. The gauge of the steel is also thicker with the larger pan. Today I measured them. The crepe pan, which doesn't need to be super thick measures .088" thick at the edge. The larger pan measures .118" thick making it 3/100ths of an inch thicker. That might not sound like much but it is noticeably thicker to the eye, and also noticeable when lifting it.
But it's a net gain for our kitchen space. It has allowed me to move out a steel wok that never really worked because of the western style, sealed top, range and burners; a cast iron wok, and the 13" CI fry pan. For now the 8" CI pan remains. Also moved out were the fire rings used with the woks to try to get them to work better and a honkin' huge lid for the steel wok. As already stated, the woks never did work right on our rangetop, and we always used the 13" CI fry pan for stir frying. The large steel pan will work even better with steels' better heat transfer. The only thing I needed to check before moving out the woks was how would we use our bamboo steamer? One of our pots fits the steamer perfectly so problem solved.
