Re: [Consdistlist] conservation of mammoth bone and tusk (Stephen Koob)

Dear colleagues, 
Do you have any idea how to consolidate [mammoth tusk] 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). 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!
Neven

I did my B.Sc. dissertation at the Institute of Archaeology, University of 
London on The Consolidation of Archaeological Bone. I found that the PVA 
emulsions were not appropriate for consolidation as they did not penetrate 
well.  I recommend the use of the acrylic colloidal dispersion, Primal WS-24, 
primarily because it is a water-based system. Depending on when the previous 
consolidation was done, it may be very difficult to remove old PVA of PVAc 
white glue.  I have also recommended WS-24 for palaeontological material.
For more information see my publications:  Koob, Stephen P., "Consolidation 
with acrylic colloidal dispersions", Paper presented to the Ninth Annual 
Meeting of the American Institute for Conservation, AIC Preprints, 1981, pp. 
86-89; Koob, Stephen P., "The consolidation of archaeological bone", Paper 
presented to the 1984 IIC Congress, Paris, Adhesives and Consolidants 
Preprints, pp. 98 102.

[Consdistlist] Open display, off-gassing material

[Eveline van Breemen]

Does building material used in an open display need to be formaldehyde
free? Or is it only necessary in an enclosed / air tight case?

We need to replace the sides and fronts of two room settings. Within the
room settings are accessioned objects. Would material containing
formaldehyde affect the objects?

Hello Neven,
I also just wanted to add my little information to your discussion, if  
it helps at all. I recently did a study looking at the mechanisms for  
damage and the affect of humidity changes on non-fossilized mammoth  
molars, which could have some useful information in it for you, "The  
Effect of Relative Humidity on Mammoth Molars." I have put it up on  
Academia.edu:(https://www.academia.edu/27784630/Examining_the_Effect_of_Relative_Humidity_on_Mammoth_Molars)
Basically, RH below about 40% causes irreversible damage to the  
structure of the teeth, which continues when the teeth are brought  
back up to higher relative humidity, a possible reason being that the  
teeth slightly powder and break at low humidity which then becomes a  
mechanical fulcrum for further damage when the teeth expand again at  
higher humidity. I can see this being a concern when trying to dry wet  
tusks as well, due to their laminar structure, and when using solvents  
that might spot-lower the moisture content (i.e. poulticing, though  
that is still probably the best bet to get off old consolidant).
In the field, for emergency conservation of wet-tea-biscuit  
consistency bone I have found Rhoplex to be of good use, as you can  
spray it on and let it soak in, at least enough to get the bone to a  
lab. I don't know if that would apply to your situation though.

Hopefully some of that is helpful and I do hope you find a solution!
All the best,

Danny Doyle
