Porcelain eye for enamel wire guide. The surface roughness of the working surface can reach Ra0.2. Due to the ceramic high hardness, the surface is smooth, so the friction coefficient is small, less demanding on site, you can pretend to guide, enameled wire sliding on the surface will not be damaged. The porcelain eye according to the requirement, I Qi cleanliness into coarse and fine polishing, polishing, single side polishing surfaces.
Ordinary cyclostomes with dipped in glaze (compact is dipped into the enamel basin, juncture along with a glazed flush immediately offered) or swing glaze (glaze slurry is injected into the blank shaking, make about evenly glazed and rapidly drained excess glaze slurry), Zhuo (relative to the "Circular", "Circular" refers to by casting molding method for round containers, such as bowls, plates, saucers and other. And molding process more complex vessels, such as bottle, respect, pots, cans, etc. is called "Zhuo") or a large circular device by blowing glaze. The bamboo covered yarn, dipped in glaze mouth blown, so repeated several times, billet surface available uniform thickness of glaze layer). The porcelain eye: time course about a day, the temperature at 1300 degrees celsius. First brick kiln gate, the ignition kiln fuel is pine firewood. The pile technology guidance, measured that looks at the fire Hou, grasps the kiln temperature change, decided the ceasefire. Glaze color such as colorful, pastel, is in have been firing porcelain glaze painted patterns, fill color, red reentry furnace with low temperature baking, temperature of about 700 DEG C - 800 degrees. In addition, before the kiln that in the blank (fetal painting, such as blue, underglaze red and so on is called underglaze red and its characteristics is the color in the high temperature glaze, never fade.
