Amalfi paper, also called Charta Bambagina, is a valuable type of paper produced in Amalfi since the Middle Ages. Documents report its presence in Italy since the thirteenth century, although it seems that the paper mills of the maritime republic of Amalfi were active before that time. Its use was forbidden in 1220 by king Frederick II as less durable than parchment. However, it continued to be produced, and in the eighteenth century twenty mills were active in Amalfi and nearby cities. Sheets of ancient Bambagina paper, despite the prohibition, survive and host documents from the fourteenth century. ==Production== Amalfi paper owes its second name, Charta Bambagina, to the specific production process which, apart from the use of cellulose from wood, is based on the processing of rags, tatters of linen, cotton and hemp white. These fabrics were once pulped with hammers moved by hydraulic-powered mills (still visible in the area). Later, more sophisticated machinery allowed greater refinement. The fiber is dissolved in water is transformed by hand into sheets by means of frames formed by wires of brass and bronze. 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「Bambagina」の詳細全文を読む スポンサード リンク
