- Résumé
- Carbon dioxide gas is an important atmospheric gas used to fumigate insect-infested museum artifacts. An object may be exposed to carbon dioxide gas in a sealed chamber for up to four weeks during fumigation. There is uncertainty about the safety to the artifacts when using carbon dioxide. There is the possibility that under conditions of high humidity within the chamber, the carbon dioxide may combine with water vapour to form carbonic acid. Though weak acid, it could adversely affect certain materials that are particularly acid-sensitive such as artificial ultramarine blue. This project investigated the effect of carbon dioxide gas fumigation on certain artificial ultramarine blue pigment samples. Two pigment samples were exposed to 70% carbon dioxide in a chamber with a relative humidity of 80% and a temperature of 25 C for 28 days. Another two samples were held in a control chamber at the same temperature and R.H. Both chambers were kept in the dark. Comparison was done on day 1 and day 28.
