The glass frit is not particularly limited. Any glass frit used as a cooking support coating composition can be used.

When glass frit is used alone as a cooking support coating composition, there is a problem of cracks occurring at 800°C.

When cracks occur, the coating material peels off, causing rust to occur on the metal inside the cooking support, and foreign substances are easily adhered to it, making it difficult to clean.

The present invention is characterized by improving heat resistance by mixing polycrystalline sapphire powder with glass frit, preventing cracks, rust, easy cleaning, and maintaining gloss on the surface.

If less than 1 part by weight of polycrystalline sapphire powder is included in 100 parts by weight of the glass frit, there is a problem that the crack prevention effect is insufficient, and even if it is included in more than 5 parts by weight, it is difficult to expect an additional crack prevention effect.

0.1 to 1 part by weight of a crack prevention effect improver may be additionally included per 100 parts by weight of glass frit.

The crack prevention effect enhancer includes 60% by weight of charcoal powder, 30% by weight of white clay, 9% by weight of granite soil, and 1% by weight of peat.

The charcoal increases the amount of negative ions, which are known to affect the parasympathetic nerves to stabilize mood and relax body tension, while promoting blood circulation, promoting metabolism, activating cell function, promoting growth, and reducing water molecules. It emits a large amount of far-infrared rays, which are known to have an activation and maturation effect, and has excellent adsorption, conductivity, and storage properties, so it is known to have the effect of blocking or absorbing electromagnetic waves when placed behind or next to home appliances such as computers and TVs. It not only blocks electromagnetic waves, but also has an air purifying effect. As it is porous, it becomes a habitat for microorganisms. In particular, actinomycetes, which are excellent at decomposing organic matter, live well, so they absorb and decompose polluted ingredients or harmful impurities in the air, purifying the air and removing odors. It plays a giving role. In addition, it is known to have purifying, purifying, and deodorizing effects. Its rich mineral content purifies water by purifying water quality and reducing water particles. It is also known to have excellent antibacterial and detoxifying effects. It is also known to have excellent antibacterial and detoxifying effects. It has a humidity control effect that naturally regulates the humidity in the living room by absorbing moisture when there is a lot of it and releasing moisture when it is dry.

The white clay has larger particles compared to clay, has lower plasticity, and has a lower content of impurities, so it is white or pink in appearance. When fired, the color is bright and it is resistant to thermal shock. The mineral phase is mostly kaolinite or halloysite.

The granite soil is soil created by weathering granite and is also called masato soil. In general, soil similar to stone powder is called Baekmasa, and soil with red clay components is called Jilmasa. The particle size is thicker than clay, so it has good breathability and drainage, so it is advantageous in controlling drying shrinkage and drying speed.

The peat is deposited without the plant material (reeds, moss, etc.) corroding or decomposing, and its main components are lignin, cellulose, etc.
