The pan is most likely made from cast iron . They are generally heavier than most other pans . They take an oil finish , meaning that one can bake or heat them slowly and then oil and season . I use garlic and olive oil in mine and never use soap on the pan as soap will remove the oil . A well seasoned pan is better than teflon , to me . One must be willing to keep the surface oiled or if you wash it , use water and ascrubbie . If you use soap , fine . Dry on the stove over a flame slowly and zap it with some oil and let cool - then wipe it out . Same process is involved with carbon steel knives , as least as far as finish goes . But carbon steel can just be wiped out after use . Well worth a try . if you find an old rusty one , BUY it . You can sand out the rust , wash well , oil and wahla !! I love making soup in my stock pot , but if I use tomatoes, do not leave sitting in the pot . Aproveche'
