Description

Technical Field

[0001] The present application relates to the technical field of glaze materials and their preparation, and in particular to a glaze material with an orange peel texture, a ceramic product containing the glaze material, and a preparation method thereof. Background Art

[0002] Traditional glaze materials are primarily inorganic silicates. New glaze materials incorporate metals or metal oxides into silicate materials, resulting in greater variations in the materials' color properties. Modern pulverization techniques allow the particle size of glaze pigment particles to reach the nanometer scale, imparting unique properties. In addition to traditional glaze materials, a variety of glaze materials with special decorative effects have emerged on the glaze market. CN107226620B discloses an orange-red glaze material with an orange peel texture and its preparation method. The material utilizes a variety of natural minerals directly for glazing. The different minerals are thoroughly mixed during high-temperature melting. During natural cooling, the different components are partially concentrated, while others separate, forming an orange peel texture. While these orange peel-forming glaze materials can reduce glaze production costs to a certain extent, their complex preparation process makes them unsuitable for mass production in orbital kilns. Consequently, their production costs remain high. Those skilled in the art continue to seek a simple, low-cost, and anti-orange peel glaze material and preparation process. Summary of the Invention
