One SS heavy copper bottom skillet, 1 No. 9 Griswold, 2 No 8 Wagner's, 2 No. 4 Wagner's, 1 5 qt CI Dutch Oven (early Lodge), 1 5 qt Nordic enamel-ware Dutch Oven, many various SS pots with copper bottoms. I cook anything in my CI, it's what it's for. Never lost any seasoning to tomato acid, etc. I don't wash w/ soap though, I use chain-mail.
My wife lets me cook anywhere and she cleans up the mess ... she's a Godsend. SJ
