I agree with you that the potential for the bags to be bad is very high. However, the problem I am concerned with is a “contact” yellowing. Therefore I find it hard to ignore that it might be something contained on the artifact or in the organic matrix that is initiating the yellowing. I am going to buy glycerin and put it on pH strips in multiple types of artifact bags (that is organics and inorganics) and see what happens.
Also, I think that we all need to monitor our collections more closely, like we have the time, yes, I know. . .I will also be initiating a system of testing soil from the sites to see if we can predict which collections may yellow the bags over time.
