Chapter 408

"Probably that's it. You can work on it first, and I'll come over to have a look when it's finished. Are you interested in colored porcelain?" Wen Dongnuan asked again.

"Cai Porcelain?" asked the old master, "What kind of conjecture did the girl say?"

"I don't have anything at hand, and I can't explain it in detail. Just imagine it as dyed fabric, or those colorful clothes worn by little girls." Wen Dongnuan said.

"Miss, do you mean that porcelain can have so many color changes?" The old master couldn't sit still and asked quickly.

Wen Dongnuan nodded, "Naturally."

"Girl, please tell me exactly what to do to make the porcelain colorful?" the old master excitedly said.

If it weren't for the difference between men and women, he might press Wen Dongnuan's shoulder now and urge Wen Dongnuan to speak quickly.

"Colored porcelain mainly has two categories: underglaze color and overglaze color. Of course, there is another kind called inglaze color. Overglaze color porcelain refers to the variety that is decorated with color painting on the glaze of fired porcelain. , which is characterized by the color on the glaze, which feels raised to the touch, including enamel color and pastel color.

Underglaze colored porcelain is a kind of porcelain that is painted with pigments on the formed carcass and fired at high temperature once after glazing.It includes blue and white porcelain, underglaze red porcelain and underglaze three-color and multicolored porcelain.

As for in-glaze porcelain, it is more complicated. There are two production methods: one is to add color or paint on the glaze, and then fire it at high temperature once.The second is to firstly burn the glazed blank at low temperature, then paint it, then spray a thin layer of glaze on the surface, and then fire it at high temperature. "

"What is the color material that the girl is talking about? Will it not fade?" Clothes will fade after wearing for a long time, not to mention porcelain. It will fade. If it fades, what is the meaning of this colored porcelain?
"It is to use metal, that is, iron, copper, etc. that we often say. For example, the content of iron is different, and there are blue glaze and black glaze respectively, and white glaze is also white porcelain. A very important element is the low amount of soldering iron. ..."

Wen Dongnuan gave examples of more than a dozen color changes, and the master's eyes were astonishingly bright.

"However, the overglaze color is because the overglaze color is painted with colored materials on the glaze surface of the fired porcelain. Such colored materials must be refined, such as azurite, stone green, cinnabar, realgar, muscovite and other minerals, as well as other minerals. Soils such as loess and white clay are good refining materials."

"We know cinnabar and realgar, and azurite and azurite... what are these?" Not to mention that the old master didn't know, even Wan Laibao and others with unusual identities heard this for the first time. "

Wen Dongnuan realized at this time that there is not a lack of first-class colors here, and she suddenly thought again, if these colors are not available, then what do literati use to paint?Is it just ink painting?
In this case, selling colored materials is also an income.

Wen Dongnuan explained a lot more blah blah blah, and even took a pen and paper to list out what he said one by one, and then gave it to Wan Laibao for him to find.

"Miss Wen, with your things, our Dayong Porcelain Kiln will definitely become the number one porcelain kiln in the entire Dahon in a short time." Wan Laibao can already imagine a bright future with endless wealth.
