Consult a Conservator
If you are affected by fires, you should retain damaged keepsakes that are still recognisable, even if damaged and dirty, as they may be salvageable. Consult a conservator before you throw them away. Conservators can be contacted via the AICCM website or through state and national cultural institutions. The AICCM is the professional organisation for conservators in Australia.
The AICCM website contains further information about the handling and care of salvaged items, particularly those damaged by fire or water.
