Jiashan brick and tile firing industry (commonly known as kiln industry) has a long history, which began in the Song Dynasty and flourished in the Ming Dynasty. According to the "Jiashan County Chronicles": Since the Ming and Qing Dynasties, the wide kiln area, the number of kiln piles, the abundance of kiln goods, and the number of employees are rare in Jiangnan. The Wanli "Jiashan County Chronicles" (1956) recorded that "bricks and tiles produced in Zhangjing are called Dongyao, and those produced in Qianjia Kiln are called this kiln. The bricks and tiles produced in the two places are not only supplied to the neighboring areas, but also mainly used by the government in Beijing, Suzhou, and Hangzhou. In the Kangxi period of the Qing Dynasty (1677), Qianjia Kiln "many people are engaged in pottery and brick filling, and the trade in the three Wus has never stopped." On March 3, the "Shenbao" of the 16th year of Guangxu (1890) recorded that "there are more than a thousand brick and tile kilns in Jiashan County, Zhejiang. During the peak sales in March and April, there are always fifty or sixty ships from Zhejiang to Huangpu, Songjiang Prefecture, or to Pudong, or to Shanghai every day, and there are no less than tens of thousands of people who make a living from this." The long-standing and developed kiln The Jiashan kiln industry has created a large army of kiln masters and firing masters, with secrets handed down from generation to generation and superb skills. They have traveled all over Jiangsu and Zhejiang, and have traveled to Anhui, Jiangxi, Beijing, Shanxi, Yunnan, Guizhou, Xinjiang, Inner Mongolia and other places to teach their skills. The Jiashan kiln industry has a long history and a unique style of kiln goods. There are many types of kiln goods, which have formed a relatively rich tile culture and are an intangible cultural heritage. According to existing physical objects and informed people, kiln goods have a wide variety of varieties due to their different uses. The "Jiashan County Chronicles" also records the varieties of Jiashan bricks and tiles: ordinary bricks include: eight-mixed, twenty-fifty, twenty-jin, paved bricks, five-jin sandwich bricks, etc. There are more than 20 kinds. Fancy bricks There are more than 10 types: Jiaputou, Sanshifang, Jiachisi, Yangzhoufang, etc. Ordinary tiles include: Fanshui tiles, Yinjin tiles, Tianhudie, Lace tiles, Wucunlushui and Toutongji, etc., more than 10 types. Jing bricks are one of the characteristic products of Jiashan bricks and tiles. Because the local soil in Jiashan contains a high amount of aluminum, and the firing masters have hundreds of years of experience, the fired Jing bricks are delicate in texture, black and shiny, strong and wear-resistant, and will not turn yellow even after a long time. The intangible cultural heritage Jing bricks are fine square bricks specially fired for the imperial palace in ancient times. Because of their fine particles, dense texture, fine craftsmanship and unique firing methods, their knocking works are very popular. The sound of gold and stone is called "gold brick". Because the bricks were transported to Beijing "Jinglun" for exclusive use in the imperial palace, they are also called "Jing brick". During the Wanli period of the Ming Dynasty, the Beijing bricks fired by Lu Tiancheng and Lu Yuancheng in Zhuhangxu Village, Hongxi Town, were quite famous. They were important materials for ancient palace buildings (paving the floor or decorating door and window frames). Now the "King of Beijing Bricks" in Yuyuan Garden, Shanghai is a new product made by Xu Jinhai, a kiln craftsman in this village. The production process of gold bricks is complicated and has a unique formula. (After the clay is dried, the surface is repeatedly rubbed with porcelain pieces, etc.), so the gold bricks soaked in tung oil after firing out of the kiln are dark and shiny, and they are as bright as a mirror after being polished for a long time.
