These are all basic terms for ceramic painting,

Since ceramics in the traditional sense are generally glazed, there will be a layer of vitreous glaze. And ceramic painting, the basic use of high temperature resistant chemical raw materials (various metal compounds)

The so-called "underglaze" refers to the ceramic carcass. Before glazing, ceramic painting (typical representative is "blue and white porcelain") is painted and then glazed. At this time, the pattern is covered with ceramic glaze. Therefore, it is called "underglaze decoration" or "underglaze" for short ".

Then, in-glaze is a relatively new name. glaze is applied to the ceramic body first, and then painted and decorated the surface of the body after glaze is applied. (I sometimes cover the glaze again after drawing to prevent the pigment from being scratched) and then fired. at this time, the painted pigment is suspended in the glaze and is called "in-glaze color", referred to as "in-glaze". in fact, glaze and underglaze, in essence is the same, are the painting process and firing together, let the color melt in the carcass, play an absolute protection, lasting constant, as long as the existence of ceramics, painting will exist.

The so-called "on-glaze" refers to the finished ceramic product after the ceramic is calcined at high temperature. At this time, the glaze layer on the surface has been formed. On this basis, the pattern is drawn with low-temperature pigment, and then baked before and after 800 degrees. The pattern at this time is attached to the surface of the ceramic glaze layer. Such a decoration process is called "on-glaze color decoration", also referred to as "on-glaze". Glaze painting, because attached to the surface, under strong physical friction or hundreds of years of long-term weathering, may be subject to abrasion.
