Problems solved by technology
Currently, to achieve a gradient effect on light-weight porcelain, it is necessary to apply light-colored, intermediate-colored, and dark-colored glazes on the ceramic body, and then fire it to achieve it. The gradient effect fired by this method The transition part of the color block is rigid in the transition part of the porcelain, and it needs to be glazed multiple times, and the glaze mixing between different color blocks should be avoided during the application process. The production process is complicated, so it needs further improvement in terms of effect and production process. Improve

Abstract
The invention belongs to the field of ceramic glaze and in particular relates to a low-temperature lightweight lime gradient glaze ceramic with the advantages of energy saving and environment friendliness and a production process of the low-temperature lightweight lime gradient glaze ceramic. The low-temperature lightweight lime gradient glaze ceramic provided by the invention comprises a lightweight porcelain body and low-temperature lightweight ceramic lime gradient glaze arranged on the lightweight porcelain body. The glaze surface of sintered low-temperature lightweight lime gradient glaze ceramic is alternated with multiple colors of milky white, grey white, light grey and dark grey and is gradually transited and is good in glossiness; gradient directions are different along with the shape change of a green body; the effect of the glaze surface can be adjusted according to formulas and the thicknesses of ground glaze and surface glaze and has a unique artistic effect; besides, green body raw materials of the low-temperature lightweight lime gradient glaze ceramic are selected according to glaze materials; the low-temperature lightweight lime gradient glaze ceramic tightly combines the green body and the glaze and can be sintered at a low sintering temperature at a time; energy saving and environment friendliness are realized, and energy consumption is reduced.
Description
technical field [0001] The invention belongs to the field of ceramic glazes, and in particular relates to an energy-saving and environment-friendly low-temperature light-weight white-gray gradient glaze ceramic and a manufacturing process thereof. Background technique [0002] Dehua is the largest production and export base of craft ceramics in the country, and most of the ceramics produced in Dehua are mainly for export. Most of the existing exported ceramics are low-temperature, light-weight and environmentally-friendly light-weight porcelain. Low-temperature light-weight porcelain is fired once, and the firing temperature is low, generally around 980-1050°C. It has strong plasticity, high ornamental value, and environmental protection. , safety and other characteristics, it is a widely favored ceramic category in the world. [0003] With the development of ceramic technology, the existing light porcelain can basically be fired at one time, such as the formula, preparatio...
