1. Quarrying for mud
Original text: However, the pottery uses fan soil as a tire, and its soil must be quarried to practice. Shixian Jiangnan Hui County, Qimen County, 200 miles away from the factory, the mountain name Pingli, Gukou, both of which produce white stone. Open cellars are taken, cut with black flowers, such as staghorns. The natives set up wheels through the stream, scooped up fine and clean, made like bricks, named "white", pure and fine color, and manufactured out-of-birth, filled white, blue and white, round and other utensils. There are several kinds of Gaoling, Yuhong, and Jiantan, each of which is named after the place of origin, and all of them belong to the territory of Raozhou Prefecture in Jiangxi. The mining method is the same as "white", which can only be used for blending and manufacturing, and is suitable for coarse and thick utensils. In the middle of the width, for mining, for scooping, for training, the method of quarrying mud is not more than a cloud.
Interpretation: The manufacture of ceramics must be made of suitable clay to make blank tires, while porcelain clay needs to be mined and refined.
Porcelain stone is produced in Qimen County, Huizhou, Jiangnan, 200 miles away from the Royal Kiln Factory, and the mountain name is Pingli and Gukou, both of which produce porcelain stones.
Open the deposit to take, which has the shape of a black flower-like staghorn. The local people use the water flow of the river to erect wheel water urns, crush the porcelain stone and make a brick shape, called "white", white is not pure in color, delicate in texture, can be used to manufacture births, white filling, blue and white and other round utensils, all kinds of porcelain.
In addition, there are a variety of Gaoling, Yuhong, and Jiantan, which are named after the names of the places of origin, and they are all produced in various places under the jurisdiction of Raozhou Prefecture in Jiangxi. They take the same method as "white", but can only be used for blending other raw materials, suitable for making thick ceramic vessels.
Second, dig up dirt
Original text: Porcelain is made of dirt, and taoism is especially pure. Saturn's stones are bound to be flawed, and the soil is loose and muddy, and it will crack. The method of tao practice, mostly soaked in mud with water tanks, stirred with wood palladium, marked up the slag sinking, passed the horsetail fine basket, and then cleared the double-layer silk bag, and then injected the mud box bowl, and the water seeped thick. With a bottomless wooden box, lay down several layers of new bricks, with a fine cloth inside, pour the thick slurry into it, tightly wrap it, the brick pressure absorbs water, the water seeps into the mud, transfers and stores large stone chips, and uses a shovel to flip and pour firmly for the purpose of making the instrument. Where all kinds of blank tires are not outside this mud, but the classification is according to the square with materials, in order to use them differently. The equipment, manual, and tracing skills contained in the canvas are available.
Interpretation: The manufacture of porcelain first requires soil, and the most important thing to cultivate soil is to achieve purity. There are tiny earthstones in the porcelain clay, and the porcelain will definitely have flaws; the porcelain clay is loose, and the porcelain will crack.
To practice porcelain clay, generally soak the soil in a water tank, stir it with a wooden palladium, remove the debris and slag floating on the water surface and sinking under the water; then filter it with a horsetail fine sieve, and then use a double-layer silk bag to clarify the water; inject the mud into a mud box bowl one by one, so that the water seeps out and the mud thickens; use a bottomless wooden barrel, lay several layers of newly fired bricks below, lay a large fine cloth inside, pour the thickened mud into it, wrap it tightly, and press the bricks on it to absorb water; after the mud seeps the water into mud, it is moved to a large stone slab, and then it is turned over with a shovel , to make the mud dense in order to make porcelain.
The production of various blank tires must use such refined porcelain clay, but the materials are added according to the formula according to the category to meet different uses.
