:''For the mercury form, see cinnabar.'' Cinnebar is a soft wood from the cinnebar tree, which grows in Southeast Asia.〔Hand Carved Cinnebar, (Jewelex.com ), Retrieved on May 2, 2008〕 ==Uses== Because the cinnebar wood is very soft it can be used to create beads, boxes and accessories by pressing a pattern into the wood. Color is sometimes added with a resin to give it more stability.〔 In Imperial China, lacquers were revered due to the time and superior craftsmanship required to produce items from cinnebar. The lacquer is created from the sap of a native Chinese tree, Rhus Verniciflua. The lacquering technique dates back 3,000 years and involves the application of up to 200 thin layers of processed sap. The sap produces a natural varnish that protects the wood. Carving the lacquer is equally arduous and is considered a true art.〔Chinese Handicrafts, (Cartage.org ), Retrieved on May 8, 2008〕 The most popularly known use of cinnabar is in Chinese carved lacquerware, a technique that apparently originated in the Song Dynasty. The danger of mercury poisoning may be reduced in ancient lacquerware by entraining the powdered pigment in lacquer,() but could still pose an environmental hazard if the pieces were accidentally destroyed. In the modern jewelry industry, the toxic pigment is replaced by a resin-based polymer that approximates the appearance of pigmented lacquer. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cinnebar」の詳細全文を読む スポンサード リンク
