Expandable Polyester Hinges for Parchment Mounting Performance in Fluctuating Environmental Conditions

The high hygroscopicity and heterogeneity of parchment make it particularly sensitive to fluctuating environmental conditions. Due to this, the final housing of an artwork on parchment, including mounting, should aim to mitigate the impact of the fluctuations on the object. The conservation of two navigation maps painted on parchment from the Musée national de la Marine, Paris raised the question of finding an appropriate mounting method. Flexible mounting techniques that adapt to the movement of parchment have been developed by conservators in the past, but their behaviour and efficiency in a fluctuating environment have not been observed or tested. This study focuses on the expandable polyester hinges method developed at the Victoria and Albert Museum and evaluates the safety and performance of this mounting technique in fluctuating environmental conditions. We explore an alternative way of manufacturing reproducible hinges using laser cutting.
