The present invention relates to a cooking vessel
processing method and a cooking vessel provided thereby, and more specifically, to a cooking vessel
processing method, which involves forming a base-
coating layer over a base that is formed at the bottom of the cooking vessel; forming a printing layer over the base-
coating layer by
pad printing or
screen printing; and forming a top-
coating layer over the printing layer, and to a cooking vessel provided by the
processing method. Conventional cooking vessels commonly use
fluorine resin based materials as a non-stick coating material, but they have a weak
surface strength (H 2~3) and the coating comes off during use or can be plasticized at high temperature (400? or above), thereby deforming the base materials.; However, a
ceramic coating method using a
sol-gel technique provides a
high surface strength (H 8~9) and a coating provided thereby does not come off even when cleaned with a scrubbing
sponge or pad or scraped down by a
metal spatula such that a cooking vessel having such a coating can be washed with water and used continuously in a hygienic manner. Further, the coating provided by the
sol-gel technique gets plasticized at a low temperature (200? or below), thereby preventing the base materials from being deformed, and the coating is possible over a variety of materials.; In the cooking vessel thus configured according to the present invention, the printing layer formed over the base-coating layer has various patterns, and the color of the printing layer changes depending on a
heating temperature being transferred to the cooking vessel, which in turn helps a user determine the temperature being transferred to the cooking vessel with the
naked eye. In addition, the top-coating layer formed over the base-coating layer contains a blend of magnetic elements such as iron,
magnesium,
cobalt and the like, and displays various patterns on the top of the cooking vessel depending on the
angle of view and attracts the interest of users.
