The present invention relates to various enamel products such as pots, tableware, and gas stove top plates. More particularly, an enamel coating layer is formed on the surface of a base material formed by using a hot rolled steel sheet for enamel, and then low-temperature drying and high-temperature sintering are performed. Then, liquid ceramic earth is sufficiently dipped for unglazing and glazing. Then, roasting is finished for ceramic surface formation on the surface of the enamel product. The present invention has the inherent toughness and lightness of the enamel product as well as excellent workability and corrosion resistance. In addition, it is possible to achieve an excellent surface durability based on the ceramic layer on the surface along with a beautiful texture and color. Because of the excellent processability of the enamel product, the present invention can be widely used as various kinds of kitchen utensils, tableware, various everyday goods such as flower pots, facility signs, and accessories not realized by existing ceramics. 본 발명은 냄비나 식기류 및 가스렌지 상판과 같은 각종 법랑 제품에 대한 것으로, 더욱 상세하게는 법랑용 열연강판을 이용하여 성형된 기재의 표면에 법랑코팅층을 형성한 후, 저온 건조 및 고온 소성 후에 액상의 도자기 흙을 충분히 디핑하여 초벌구이 및 유약을 디핑한 후 재벌구이를 마쳐 법랑 제품의 표면에 도자기 표면이 형성되도록 제조함에 따라, 법랑 제품이 갖는 고유의 강인성과 가벼움은 물론 우수한 가공성 및 내식성을 그대로 갖고 있는 것은 물론 표면의 도자기 층으로 인해 뛰어난 표면 내구성은 물론 미려한 질감과 색감을 그대로 연출할 수 있는 것이고, 법랑 제품이 갖는 우수한 가공성으로 인해 기존의 도자기가 실현하지 못한 각종 주방용품 및 식기류 혹은 화분을 포함한 각종 생활용품은 물론 시설 안내판이나 장신구 등으로 광범위하게 활용할 수 있는 효과가 있는 것이다.
