Huang Wenchong said that the iron content of Jianye is above 8%. In the process of high temperature melting at 1300℃, the change of kiln temperature caused strange patterns on the glaze. The same raw materials, put in different kilns, produce different patterns and glaze colors in different seasons and different weather, which are unpredictable. Therefore, each building has a different look, each building has a unique personality, each building is unique and is an orphan.
"Making lanterns is an art that combines earth and fire with difficulty." Huang Wenchong said that the firing process of the sword lantern is complicated, and it has to go through three production processes, such as mineral processing, porcelain ore crushing, elutriation, batching, aging, mud refining, mud kneading, blank drawing, blank cutting, plain firing, glazing, kiln loading and roasting, and the four major firing elements must be coordinated. Glaze color is the most attractive part of building a lamp, and it is also the most difficult part in building a lamp. Because the crystalline glaze is difficult to control in the high temperature of the kiln, and the blank with high iron oxide content can't stand the high temperature, it is extremely difficult to burn a building lamp with flawless appearance and beautiful markings. Only by firing tens of millions of architectural lamps in the Song Dynasty can we occasionally get one or two of the most precious obsidian lamps; One or two oil drop lamps need millions of building lamps.
"Jianye is still the only tea set for tea." Huang Wenchong pointed out that due to the high iron content of Jianzhan, the iron content is generally 10%, and the magnet can be adsorbed on the bottom. When making tea, its magnetism can soften the water quality and has a health care effect on the human body.
Huang Wenchong said that other antique porcelain products are mainly used for viewing, while teapots and lanterns built in the Song Dynasty, which were popular in the Ming and Qing Dynasties, still have high use value, so people pay more attention to these ancient tea sets. The higher prices on the market are also beautiful architectural lights. He took out a hat-shaped lantern that he treasured. For example, he received it at the end of 20 13, and the price at that time was tens of thousands of yuan, because the shape was exquisite. The tea bowl pays attention to stability, but the bottom of this hat is very small, just the size to hold the tea cup steadily. The right shape is very pleasing. "This is my baby, I won't change money." Huang Wenchong said with a smile.
Huang Wenchong also showed some new black porcelain teacups to reporters. "These are all newly fired by Jianyang," he said. Different from other famous kiln mouths, Jianyang kiln mouth declined after the rise of the Song Dynasty, and it has been seven or eight hundred years since the kiln mouth stopped making lanterns. After 20 10 years, due to the increasing collection of lanterns in the market and the local high-quality black clay, more and more people reopened the kiln mouth and re-fired black porcelain tea sets. But now most of them are fired by electricity, which heats up quickly and the tea set is heated evenly. Except for some well-known artists in China who use hand-painted blanks, many mass-produced products are mainly fired by molds, and the form is relatively dull ~
