The high-temperature melting length refers to the length of the slurry flowing on an inclined plane after being dried and hydrated, 4.3g of glaze is ground, pressed into a cylinder shape, placed on a frame with an inclined angle of 45 degrees for firing and melted at high temperature. When the high-temperature melting length is shorter, the sintering temperature required by the first component glaze is higher, and the bonding property between the green body and the first component glaze is poor; when the high-temperature melting length is too long, phenomena such as glaze flowing and the like can be caused. The high-temperature melting length of the first component glaze is characterized by: the method comprises the steps of fixing the weight and the firing condition, and obtaining the high-temperature melting length of the first component glaze after glaze firing, wherein the high-temperature melting length and the whiteness of the glaze are controlled by adjusting the using amount of each component, and the high-temperature melting length of the first component glaze is dynamically regulated and controlled by adjusting the using amount of calcined kaolin, so that the length range is kept between 8 and 15mm, if the length range is exceeded, the using amount of calcined kaolin is increased, and if the length range is lower than 8mm, the using amount of calcined kaolin is reduced. The high-temperature viscosity can be adjusted by regulating and controlling the silicon-aluminum ratio and the dosage of fluxing agents such as alkali metals, alkaline earth metals and the like, silicon-aluminum in a high-temperature melt has the refractory characteristic as a glaze framework, and silicon-oxygen bonds are destroyed by adding alkali metals (potash feldspar) and alkaline earth metals (calcite and calcined talc) to realize melting.

The calcined kaolin used in comparative example 2 was decreased and potassium feldspar used in comparative example 1 was increased compared to comparative example 1, and the high temperature melt length of comparative example 1 was less than 8mm and that of comparative example 2 was more than 15mm. Example 4 compared with example 2, the amount of the calcined kaolin is correspondingly reduced while the amount of the zirconium silicate is increased, the whiteness is improved, and the high-temperature melting length can be basically maintained unchanged. The high-temperature melting lengths and the whiteness of the embodiments 1 to 7 are both suitable, and the glaze effect of the embodiment 3 is optimal.
