Soapstone Saute Pan and Lid with Copper Band and Handles. Naturstone is not a composite; each pot is hand-crafted entirely from one block of soapstone. Once seasoned this pot's naturally non-stick surface will not react to food acids, so there is no breakdown, discoloration or imparted odor or taste. The dense stone stores and radiates heat (and cold) longer than any metal or clay cooking material; and spreads the heat as evenly as copper. So foods cooked in Naturstone pots display their fullest flavor. Great for slow-cooking, but strong enough to fry in. The pot darkens to a lustrous black with use. Oven, stovetop, grill safe.
