Characteristics of acid immersion glaze of Jianzhan

The glaze of acid-washed porcelain is very clean and smooth. The glaze of ceramic products consists of a ceramic layer and a glaze layer, and the glaze layer is covered on the surface of the ceramic layer by mixing nano-materials and glaze paste.

Looking at the glaze layer on the surface of porcelain under a hand-held microscope, the wear (ox hair lines) on the surface of old porcelain is criss-crossed, and the thickness is different, but the new porcelain does not have this phenomenon. Some counterfeiters use sandpaper to wipe, and the lines, directions and strengths are similar. Any porcelain treated with hydrofluoric acid can see countless holes corroded by acid under the microscope.
