Background
In recent years, with the improvement of living standard of people, the decoration quality requirement of modern home decoration level is continuously improved, and the traditional decoration level can not meet the requirement of people. As early as Song dynasty, there were rare microcrystalline glaze, placer gold glaze, temmoku glaze and eel skin green. The alluvial gold glaze is a kind of noble glaze, and owing to the characteristics of alluvial gold glaze, gold plate crystal or metal powder is suspended in the colored transparent glass glaze, and the glaze twinkles under the irradiation of light to make the glaze have different colors. This feature is of increasing interest to a growing number of people. The luxurious living room is decorated by the porcelain glaze ceramic tiles, so that the indoor environment forms a refulgent and brilliant artistic atmosphere which is rather popular with people.
The alluvial gold glaze is a transparent vitreous substance containing thin mica-like flakes or glittering crystals suspended in a transparent glaze layer. The crystals have different surface directions and give people bright and glittering feelings due to reflection of light, and the crystals are similar to the gulmite in the mineral, so that the crystals are named as the gulch glaze. The crystallization of iron oxide in the alluvial gold glaze is generally considered to be the dissolution of iron oxide in the glaze at high temperature to form a supersaturated solution of iron, which is then precipitated under appropriate conditions. Different glaze effects can be produced due to different process control. For this reason, there are differences between rabbit hair glaze, raindrop glaze, iron red gold ring glaze and sand gold glaze. Generally, the formation of the alluvial gold glaze is caused by decomposition, enrichment and crystallization of iron oxide in the glaze under certain conditions in the firing process.
At present, the alluvial gold glaze has quite a plurality of defects, for example, when the alluvial gold glaze is used in the field of daily ceramics, the high cost and the heavy metal materials contained in the alluvial gold glaze are not beneficial to human health.

preparation of S2 slurry: mixing the glaze materials, and mixing: ball: water = 1: 1.5-2.1: ball milling is carried out for 20-40min at the proportion of 0.4-0.8, and then the mixture is sieved by a sieve with 150 meshes and 200 meshes to obtain slurry;
s3 glazing: glazing the slurry obtained in the step S2 on a ceramic blank, and drying at the temperature of 40-50 ℃;
s4 firing: and putting the dried green body into a kiln, raising the temperature to 600 ℃, preserving the heat for 1.5h, then raising the temperature to 1100-1250 ℃, preserving the heat for 2.5-4h, and finally naturally cooling the green body in a room at the temperature of 20-30 ℃ to room temperature to obtain the cast iron sand gold glaze ceramic product.
Further, the preparation process of the iron sand in the step S1 is as follows: and putting the waste iron slag into a quenching device for heating quenching treatment, putting the waste iron slag after heating quenching into a crusher for crushing to obtain an iron sand semi-finished product, and screening and classifying the iron sand semi-finished product to obtain the finished product iron sand.
Further, the glazing manner of step S3 is dipping.
Further, the thickness of the glaze layer in the step S3 is 0.5-0.8 mm.
The invention has the beneficial effects that:
the invention adopts lead-free and nontoxic raw materials, which is beneficial to human health; the invention adopts the waste iron slag to replace iron oxide as the glaze, greatly reduces the cost, and simultaneously, because the boron frit is added, the boron frit can be used as a fluxing agent, effectively reduces the high-temperature viscosity of the glaze, increases the fluidity of the glaze, has the phase splitting effect, can reduce the firing temperature of the glaze, and achieves the purpose of saving energy, and the boron frit can play a better phase splitting effect under the weight ratio provided by the invention; the proportion of titanium oxide adopted by the invention is beneficial to the crystallization of ferric oxide, because titanium oxide and boron clinker generate phase separation, and the phase separation is beneficial to the crystallization and growth of crystals under proper conditions to obtain a very obvious glaze surface alluvial gold effect, but the crystallization of the crystals is hindered by too high content.
