En jämförande studie mellan två våtrengöringsmetoder på papper

Abstract

Amongst the published literature researching wet cleaning of paper there is a limited amount of studies conducted researching the method simmering water treatment. There are even less studies conducted on how simmering water affects the paper being treated when used as a cleaning method. Despite the limited research, there are literary reviews describing the method and suggesting it as an alternative for conservation of paper with iron-gall ink. The following study will therefore be examining, the somewhat unusual method, simmering water treatment, and comparing it to one of the more common wet cleaning methods: immersion washing. This is done to compare how the different temperatures of the water affect the paper. The types of paper used in this study consists of three dyed and four undyed papers. All of the papers are new, apart from one sample originating from 1847. The study aims to investigate how methods affect the dimension, the coulouring and opacity of the papers. To examine how these aspects of the paper change before and after washing, the following analytical methods are used; the dimensions of the papers are measured using a ruler, thickness gauge and scale: the colour of the papers is analysed with a colorimeter, which is done before and after the washing treatments: the water from the different baths is collected and analysed before and after completed treatments, using pH- and conductivity meters. The results from the study show that simmering water treatment and immersion washing affect the papers differently. The most apparent changes between the different methods, before and after washing, can be seen in the dimensions and the colour of the papers.
