Pigment formula of overglaze blue-and-white and processing method

The invention provides a processing method of a pigment formula of over-glaze blue-and-white, the final color of a coloring agent is greatly influenced by other components added into the coloring agent, in order to make each batch of ceramic pigment have the same color, raw materials with the same mass must be finely weighed and mixed according to the composition, and the materials are put into a mixing tank to be mixed; calcination is an important process for preparing a product and aims to stabilize the product, in the calcination process, different reactions occur due to different properties of raw materials and different expected ceramic pigments, and the lowest calcination temperature is the same as the use temperature of a final pigment product. When the overglaze blue-and-white pigment is used, the overglaze blue-and-white pigment can become a color which can be normally produced without being influenced by climate and environment across the country, and when the pigment is used, the firing temperature
