Abstract
The following study tests for the effects of mordants on the production of restoration papers during the conservation process of damaged paper artifacts. For this, four different types of synthetic mordants that are being marketed currently ($K_2CO_3$, $AlK(SO_4)_2{\cdot}12H_2O$, $Cu_2SO_4{\cdot}5H_2O$, $FeSO_4$) were selected to produce samples for measuring variable properties through artificial degradation. The research conducts tests for changes in color, tensile index, and pH level (degree of acidity). The results for changes in color have shown that the value of ${\Delta}E^*ab$ of $K_2CO_3$ mordant sample was the highest, and the tests for tensile index have shown that the strength of dyeing sample was decreased in accordance with the aging time, but Changes according to the mordant was not evident. Finally, the findings for pH level have shown that samples with $Cu_2SO_4{\cdot}5H_2O$ and $FeSO_4$ have pH levels drop below 6. As a result, the research have concluded that mordants used for dyeing restoration paper were identified to have an affect in the dyeing and aging characteristics of the paper.
