What are the classification standards for bone china cups? | Win-Win

October 18, 2022

Inconsistencies in the classification of bone china cups have been attributed to inconsistent classification criteria. We call it "high temperature glaze". In fact, this is the same concept in two different formulations, and there is no contradiction between the two. And it is mentioned that the Chinese traditionally named glaze should be the definition of the Qing Dynasty, re-glazing, and then calcined. Win-win Ceramics' views were also supported and recognized, and physical samples were analyzed and demonstrated. The difference is that Win Win Ceramics believes that the stencil-applied brown spot color ware is an on-glaze color.


The win-win company believes that the difference between the above bone china cups lies in the naming standard of the color porcelain category! Finally, the process of colouring the porcelain before firing, the sequence of colouring and varnishing processes and the resulting glazing relationship should be named. Or is it named after the final practical effect of the color-glaze relationship after the bone china is fired? The latter nomenclature should be correct in a scientific sense, as it reflects the essential characteristics of the final outcome of things, rather than the process by which things have variables. Using this principle and the criteria for the relationship of the glaze after firing as a criterion, we can clearly define: the color material is under the glaze and is tightly bound to the tread is the underglaze color; the color material is combined with the different carcasses. The middle of the upper and lower glaze is called glaze. The tinting material is cured on the glaze and the whole or part of it is directly exposed. It is worth noting that the color of the high temperature glaze and the color of the high temperature glaze are the same as the color of the glaze, but due to the thickness of the glaze layer and the color of the kiln temperature, there are three different firing effects:

1. The glaze layer is very thin. The pigment is thick and the kiln temperature is low. Those who cannot sink all the glaze into the glaze usually turn into a high temperature glaze.

2. The glaze layer is thicker. The color of the lacquer is thin and the temperature of the kiln is high, so all the colorant sinks into the glaze and is enclosed by the glaze.

3. The same color material is used on the same object, and the pattern drawn by the same method is partially fired and partially fired. Therefore, there is no absolute boundary between the two.
