PURPOSE:To provide a burner which is discernible in its heating condition by users, has an attractive appearance, is excellent in corrosion resistance and is easy to be processed by mixing temperature-dependant color changing material, which reversibly changes its color at a predetermined temperature, to the burner cap made of ceramic material. CONSTITUTION:A stove burner comprises a burner cap 1, a mixing tube 2 and a burner body 3. The burner cap 1 has the ceramic base material such as Al2O3, SiO2 and ZrO2 which is mixed with metallic complex such as Co and Ag or temperature-dependant color changing material which reversibly changes its color depending on the temperature, the mixed material being fired. When the burner cap 1 is heated upon ignition and reaches at certain temperature, the color of its external surface changes. The double salt of Ni, for instance, changes the color from yellow to red at 110 deg.C, and the complex salt of cobalt or nickel and amines from blue to pale pink. By mixing color changing material like this, the heated condition of the burner cap is visually displayed. Further, as ceramic material is used, an excellent corrosion resistance is obtained. |
