20.500.12556/RUL-155400 An art technical study and examination of mediaeval Islamic paper colouring techniques lecture In this study, the materials and techniques used in the colouring of mediaeval Islamic paper from the 10th through 19th centuries were examined, and red- and yellow-coloured historical papers were chemically analysed. The tested colouring method was based on recipes for paper colouring provided in seven unpublished, previously untranslated into English, original Arabic historical sources. Liquid chromatography was used for dye identification. The results of more than 50 recipes from historical sources suggested that ~30 raw materials were used for colouring paper, including four for dyeing paper red and four for dyeing paper yellow. To verify this information, several different techniques were used to extract the dye from the raw material and then reconstruct the dyed paper samples. Preliminary results, obtained using high-performance liquid chromatography with diode array detection, demonstrated the potential of this method to identify the natural dyes historically used for Islamic paper. Henna and madder were identified in two historical paper samples, based on the detection of lawsone and alizarin respectively. natural dyes HPLC-DAD dyeing Islamic paper historical sources Mediaeval time naravna barvila HPLC-DAD barvanje islamski papir zgodovinski viri Srednji vek true false true Angleški jezik Slovenski jezik Drugo 2024-03-29 11:50:29 2024-03-29 11:50:30 2024-03-31 15:16:38 0000-00-00 00:00:00 2023 0 0 10 str. 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 543.544.5HPLC:667.27 166910723 166896643 RAZ_Ebeid_Hassan_2023.pdf RAZ_Ebeid_Hassan_2023.pdf 1 0D9336CBCF8DAEE30632DDDF3B7C1A9E 991958af9adc2ac75edb189cab2f5726ec7bb78c0037b2f660bc3393c3683dc8 33e1ecee-edbb-11ee-b5ba-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=182268 https://icom-cc2023.org/papers/ Prispevek dostopen le z geslom 1 29f441dc-edba-11ee-b5ba-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=182266 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
