Innovative Production of Lead-Free Wood Leafhopper under High Temperature Firing Environment

Abstract

The lead-free wood leafhopper is the iconic traditional ceramic art of the Jizhou kiln in the Song Dynasty of China. The traditional lead-free wood leafhopper is usually made of black glaze. The glaze is placed on the mulberry leaf and fired at a high temperature of about 1230 °C-1260 °C. And the veins are clear. Jizhou kiln was founded in the late Tang Dynasty. It flourished in the Five Dynasties and Northern Song Dynasty. It was the most prosperous in the Southern Song Dynasty. It began to decline in the late Yuan Dynasty and then stopped for more than 700 years. However, its unique artistic value has gradually be attracted the attention by the world. And it recovered in 1985 at last after unremitting efforts. The re-burning of the lead-free wood leafhopper has successfully opened the ceramic market of the lead-free wood leafhopper and made it occupy a certain position in the ceramic market. The price of lead-free wood leafhopper has remained high, and therefore ceramic producers are waiting for opportunities to produce on a large scale in order to achieve huge economic benefits. However, due to the great difficulty in the firing process of the lead-free wood leafhopper, the market has a phenomenon of low yield, high price, low consumer desire, and the use of chemical materials to fire products. The subject analyzed and solved these phenomena through a large number of experiments. Lead-free in this subject is a relatively broad definition, especially referring to the new type of lead-free wood leafhopper without contain heavy metals.
