摘要

摘要:本文提出植物岩是鉴别中国手工纸纤维来源的重要材料。为了进行初步的方法论探索,我们收集了两种未经加工的宣纸和两种用于制作宣纸的植物材料——稻草和蓝檀香树皮。采用干法灰化法从生玄及其植物原料中提取植物岩。结果可以总结如下。首先,水稻(Oryza sativa)的植物岩特征在水稻秸秆和生玄中都很丰富。通过寻找水稻植物岩,可以判断特定纸张中是否使用了水稻秸秆纤维。其次,在蓝檀香树皮中观察到相当数量的毛细胞植物岩,但在被检查的论文中没有。热实验表明,蓝檀香中的植物岩耐长期高温,在造纸过程中(热源仅高于200°C),它们不太可能被消除。据推测,它们在碱性(石灰水)中煮熟时会溶解。进一步的研究是必要的,以了解在石灰水中煮熟的蓝檀香中的植物岩是否会发生形态变化,如果是,是如何发生的。图形抽象

Identifying sources of fibre in Chinese handmade papers by phytoliths: A methodological exploration
ABSTRACT This paper proposed phytoliths as promising for identifying and distinguishing sources of fibre in Chinese handmade papers. For an initial methodological exploration, two types of Raw Xuan (unprocessed Xuan paper) and the two plant materials used in making them—namely rice straw and bark from blue sandalwood (Pteroceltis tatarinowii Maxim.)—were collected. The dry ashing method was used to extract phytoliths from Raw Xuan and its plant materials. The results can be summarized as follows. First, phytoliths characteristic of rice (Oryza sativa) were abundant in both rice straw and Raw Xuan. By looking for rice phytoliths, it is possible to tell whether or not rice straw fibre is used in a particular paper. Second, hair cell phytoliths were observed in considerable quantities in blue sandalwood bark, but absent in the examined papers. Heat experiments showed that phytoliths in blue sandalwood were resistant to long-term heat and they would unlikely be eliminated when exposed to the heat in papermaking (with heat source barely above 200°C). It is hypothesised that they dissolved while cooked in an alkaline pH (limewater). Further studies are necessary to understand whether phytoliths in blue sandalwood—while cooked in limewater—undergo morphological changes and, if yes, how. GRAPHICAL ABSTRACT
