Abstract

The invention discloses a high-temperature iron sand gold glaze, which comprises the following raw materials: 30-40wt% of potassium feldspar, 9-15wt% of kaolin, 8-15wt% of a phase-splitting crystallization agent, 0-5wt% of barium carbonate, 2-6wt% of dolomite, 15-25wt% of glass powder and 12-20wt% of iron oxide. In addition, the invention further discloses a preparation method and application of the high-temperature iron sand gold glaze. Through formula design, the system has a high melting crystallization temperature and a large melting temperature range under an oxidizing atmosphere condition, so that the defects of poor chemical stability, low glaze hardness and the like of a glaze surface are effectively solved, and the glaze layer is compact in structure and high and uniform in crystallization degree while having good chemical stability and high glaze surface hardness, and the performance requirements of domestic ceramics such as high-temperature tea tableware and ceramic ornament decoration can be well met.

Description

technical field [0001] The invention relates to the technical field of ceramic glazes, in particular to a high-temperature iron placer gold glaze and a preparation method and application thereof. Background technique [0002] Sand gold glaze, also known as gold sand glaze, is called Venus glaze in Hebei, Shandong and other places in China. The shiny metal flakes and star points in the glaze are a small crystal crystal formed in the glaze layer. Like the natural aventurine produced in Norway, it sparkles under certain light, hence the name. In recent years, with the improvement of people's living standards, the decoration level and decoration quality requirements of ceramic products are also improving, and the traditional decoration level can no longer meet people's needs. As early as the Song Dynasty, there were precious microcrystalline glazes --- "placer gold glaze", "Tianmu glaze" and "eel skin green". Gold placer glazes consist of thin mica-like scales, or shiny and re...
