Dear colleagues, a few months ago a local diver brought a piece of mammoth tusk (60x30x30 cm) to our Museum which he took out of nearby river. We have kept it in water ever since, and now the time has come to conserve it because it will be featured in an exhibition. do you have any idea how to consolidate it without using solvents such as ethanol or acetone? We would prefer to use a water-based system because of health risks. Also, a large part of our mammoth bones collection was treated in sixties by immersion in diluted PVA or PVAc glue (white thick wood glue). The glue is now flaking of the object, taking with it small particles of bone. Do you have any idea how to chemically remove it without affecting the very porous bone? Also, do you have any suggestions on how to consolidate bone previously treated in this manner?
Thank you all!
