Moonlight stone glaze, glazed tile with moonlight stone effect on surface and preparation method of glazed tile

The invention relates to the field of architectural ceramics, in particular to a moonlight stone glaze, a glazed tile with a moonlight stone effect on the surface and a preparation method of the glazed tile. The moonlight stone glaze comprises the following chemical components in percentage by mass: 15%-19% of aluminum oxide, 53%-58% of silicon dioxide, 2.8%-3.5% of potassium oxide, 1.5%-2.2% of sodium oxide, 6%-10% of calcium oxide, 2.5%-4% of magnesium oxide, 0.1%-0.5% of ferric oxide, 0.2%-0.6% of titanium dioxide, 0.2%-0.8% of cobalt oxide, 0.6%-1.5% of neodymium oxide, 0.3%-1% of copper oxide and 6%-9% of ignition loss. Preferably, the initial melting temperature of the moonlight stone glaze is 1080 to 1120 DEG C. During firing, the moonlight stone glaze permeates into the bright glaze layer to generate a gradually-changed yellow-blue halo, so that a moonlight stone effect is generated on the surface of the ceramic tile. 本发明涉及建筑陶瓷领域，具体涉及月光石釉、表面具有月光石效果的釉面砖及其制备方法。月光石釉的化学组成包括：以质量百分比计，三氧化二铝15～19％、二氧化硅53～58％、
