Problems solved by technology

However, the current production of Ru porcelain is still mainly based on antiques, and there are still some deficiencies in its production technology.
In the production process of Ru porcelain, the small utensil-shaped Ru porcelain tea set is two-way split. Due to the long-term use of the tea set, it is easy to leave tea stains on the cracks inside the tea set, which affects the use of the tea set and affects the appreciation of Ru porcelain. The value of sex and crafts

Abstract

The invention provides a preparation technique of jade bluish white porcelain, which comprises the steps of: using Datong soil, black soil, feldspar, quartz, argil, sandstone, bovine bone and kaolin as blank body raw materials; crushing the blank body raw materials, adding water to grind the same, and adjusting the water content of the slurry to 29-33%; crushing a glaze raw material, adding waterto grind the same, and adjusting the water content of the slurry to 58-60%; injecting the slurry in a mould, trimming and taking out the burnt biscuit for future use; soaking glaze on the outer surface of the biscuit; putting the blank body in a kiln furnace, burning the same in an oxidization atmosphere, heating the furnace to 1200 DEG C, reducing the ventilating quantity of the kiln furnace to convert the interior of the furnace to a reducing atmosphere, controlling the temperature to 1200 DEG C, burning the blank body for 40 min, gradually heating up at a speed of 1 DEG C per minute, burning the blank body at 1268-1270 DEG C for half an hour in a holding manner, and stopping the fire to finish the preparation technique. The burnt Ru porcelain has a beautiful body color, and the exterior thereof is cracked while the interior thereof is not cracked.

Description
