A cookware, in which the overall surface of a main body made of metal is hard-anodized for preventing corrosion, a natural stone is placed from the bottom surface of the main body to a designated height of the main body for improving a thermal insulation property and discharging mineral matters, and hand grips are riveted at the outer surface of the upper end of the main body, which is not provided with the natural stone, for allowing a user to easily lift the cookware. The cookware includes a main body having a space for containing food to be cooked, and provided with a plurality of installation holes formed through the upper end thereof; a coating layer obtained by hard-anodizing the overall surface of the main body for preventing the main body from corroding and improving thermal conductivity and strength of the main body; a natural stone placed in the main body such that the natural stone contacts the bottom surface of the main body to a portion of the main body below the installation holes for transferring external heat or mineral matters to the food; and hand grips integrally connected to the main body by rivets inserted into the installation holes after the coating layer is formed. The hard-anodizing treatment improves the strength of the main body, prevents the main body from being scratched and the natural stone from being separated from the main body, and improves the strength of the hand grips.
