Abstract

The invention provides a leopard spot glaze with a wide sintering range. The glaze comprises ground glaze and cover glaze, wherein the ground glaze is prepared from the following components in parts by weight: 30-70 parts of basic transparent glaze, 3-7 parts of MnO, 4-7 parts of Fe2O3, 3-5 parts of Cr2O3 and 30-50 parts of low-temperature clinker; and the cover glaze is prepared from the following components in parts by weight: 20-50 parts of basic transparent glaze, 8-10 parts of vanadium-zirconium blue, 3-5 parts of ZnO and 50-80 parts of low-temperature clinker. The glaze has a wide sintering range, has vivid leopard spot decorating effect, and can well enrich the decorating means of art and craft ceramics.

Description

technical field [0001] The invention belongs to the field of preparation of ceramic glazes, in particular to a leopard-spotted glaze with a wide sintering range and a preparation method thereof. Background technique [0002] In recent years, with the continuous improvement of people's living standards, people's demand for various art ceramics has steadily increased, and at the same time, the requirements for the appearance and glaze decoration of various arts and crafts ceramic products have also increased. Ceramic glazes with strong body adaptability, rich colors and vivid images have always been the direction of efforts of ceramic craftsmen. The existing leopard-spot pattern and color glaze effect is formed by first applying a base glaze on a relatively fixed ceramic body, and then manually drawing a spot pattern and color glaze on the bottom glaze and firing it. The leopard spot glaze obtained by this method has poor adaptability to ceramic bodies with different firing t...
