Longquan kiln is a famous kiln in Chinese history, one of the five Song Dynasty kiln system. It already has 2,000 years of history, is one of the longest porcelain kilns in Chinese history. Because the original way of making ceramic yield and glaze firing are different, it tends to be more heavy, more delicate in detail, compared with gas-burning monotony, it will be more surprises.
Kind of unknown and unpredictable surprises is the biggest reason to protect and hand down this.
However using firewood to make original longquan ceramic is a long process, generally only once a year. From start to finish, in strict accordance with the traditional method is not easy.
First is material. Prospecting the soil in the mountains with a blank, and then finely ground ore stone by hand, because Longquan celadon glaze almost harsh, just one process does not meet the standard, the finished porcelain is defective.
Another is troller. For porcelain people know carved flower, engraving, relief, all kinds of insects beast dough decorative techniques are required to be well versed.These skills are no shortcuts, it is built up little by little.
Before loading into the furnace, each porcelain should be carefully checked if every part is so perfect. The whole process requires adequate firewood must be a combination of pine and hardwood, workers need to be prepared in advance and let the firewood sun-dried into a dry sufficient degree.
Firewood needed to complete by more than 20 master together, needs a total of about 30 hours of continuous firing, when need put more firewood , when released, these are very particular about. All depends on the porcelain people’s eyes to make decisions.
But this skill as gradually been forgotten. Although Longquan celadon got by the United Nations World Intangible Cultural Heritage, but I think this not enough. I hope this craft can be protected to give the inheritance, so that more people can learn the most traditional Longquan celadon firing method, see the most beautiful celadon jade.
