[0049] A method for preparing a full-polish glaze with an iridescent flash effect, which is used to prepare the above-mentioned full-polish glaze with an iridescent flash effect, comprising the following steps:
[0050] Step (1): Add the transparent basic glaze to the ball mill, add water to control the solid content of the transparent basic glaze, the amount of water added can be determined according to the actual situation, this program can preferably control the solid content of the transparent basic glaze to be more than 72% by adding water, Adding a ball milling agent for ball milling, the milling fineness is less than 0.2% on a 325 mesh sieve, stale, and a transparent basic glaze glaze slurry is obtained;
[0051] The milling fineness will be fine enough to ensure that the maturing temperature of the glaze is not too high; the ball milling agent is a known ball milling agent added as needed in the ball milling process, such as sodium tripolyphosphate and sodium carboxymet...

[0062] The chemical composition of the transparent base glaze, calculated in mass percent: 45.80% SiO 2 , 9.70% Al 2 o 3 , 9.78% CaO, 1.54% MgO, 0.31% K 2 O, 4.19% Na 2 O, 11.84% of ZnO, 4.41% of BaO, 2.70% of SrO and the rest are lost on ignition.
[0063] The purity of barium sulfate in barite is 95%; the purity of strontium sulfate in celestite is 95%, and the purity of Na feldspar 2 O content is 9.30%, K 2 The O content is 0.01%; the particle size of zircon sand is between 80-120 mesh, of which, by mass percentage, 80-90 mesh is 30%, 90-110 mesh is 50%, and 110-120 mesh is 20%. %;
[0064] The dry material of transparent base glaze, zircon sand and ink are mixed according to the mass ratio of 8:1:1.
