Hi list.

Just received the current Historical Archaeology. (VERY nice, Julie...) 
Does anyone have experience with the effects of the standard process of 
washing durable artifacts in water, perhaps accompanied by light to 
moderate scrubbing with a tooth brush? I'm particularly interested in the 
effects on remnant DNA and on chemical traces, particularly traces of the 
various drugs derived from the opium poppy. Everyone SAYS morphia use was 
wide-spread in the 19th century. We should, now or eventually, be able to 
test bottle glass for its traces and test that "everyone says".

Lacking experience, does anyone have an opinion? (Do archaeologists have 
opinions??:)
