Your Carbon Steel cookware will work with induction cooktops. It is good practice to use the appropriately sized element (or eye) in relation to the diameter of the cooking base. The eye should not be smaller in diameter than the pan base. Too small of an eye can concentrate heat in a small area and cause the steel to expand and contract at a different rate than the surrounding area and lead to warpage. Be sure to ramp up the heat gradually as rapid heating may lead to warpage.
