The present invention relates to a super-smooth glaze and a preparation method thereof, and belongs to the field of ceramic machining, wherein each component in parts by weight is: potassium feldspar, quartz, kaolin, calcite, dolomite, boric acid, aluminum oxide, silicon oxide, calcium oxide, potassium oxide, sodium oxide, zinc oxide, and barium oxide; a mixture weighed in proportion is disposed in a planetary quick ball mill, and pure water of 30˜40 wt % to the total weight of the mixture is added to ball-mill the mixture to particle sizes of 0.5˜1.0 μm, thus obtaining the super-smooth glaze. The method enables the surface of a glaze layer to be highly smooth and makes the roughness of the glaze be relatively reduced than that of an ordinary ceramic glaze.

Procedure for controlling the chemical reaction in multi-layer ceramic decorations, according to interfacial and surface properties, in which the ceramic coating formulation is broken down into two separate compounds: on the one hand, a bottom layer formed by a glaze with part of the necessary oxides to obtain the ceramic effect, applied in the conventional manner over the ceramic substrate, and on the other hand, a top layer formed by an ink with the other necessary part of the oxides, applied by injection over the previous layer. The ceramic product is finished off with a firing process. This procedure has the advantage of regulating the penetration of the oxides of the top layer throughout the profile of the bottom layer, thus achieving an adequate concentration of oxides in the zone nearest to the surface, which permits optimization of the chemical reaction and thus, of the ceramic effect obtained.
