A disclosed super-smooth thick glaze is composed of frit and a raw material with a mass ratio of (10-30):100. The super-smooth thick glaze is composed of the frit with good high-temperature fluidity and a part of the raw material, so that a glaze surface is capable of rapidly levelling at a high temperature and is good in fusion performance. Through matching of different materials, the glaze surface is small in high-temperature viscosity, and a gas in a glazer layer is facilitated to be exhausted, thereby guaranteeing the smooth effect of the glaze surface and relatively small and less glaze-layer bubbles. Detection results show that a super-smooth thick glazed porcelain tile prepared from the super-smooth thick glaze has less and small bubbles and relatively good glaze-layer transparent feeling because has the bubble quantity in a vision field with a diameter of 1.6 mm is 1-3 and the diameter of the bubbles is in the scope of 0.02-0.06 mm. The super-smooth thick glazed porcelain tile subjected to polishing has the glossiness of 105 DEG -110 DEG higher than 95 DEG -100 DEG which is the glossiness of common fully-glazed porcelain tiles.
