I'm glad to hear I wasn't too off base with my thinking and there's been some really good suggestions I hadn't considered, such as using ethanol rather than water or heat to remove the final excess while avoiding wetting or creating a shiny surface. Thanks again.

It's a piece of wood which was midway through conservation treatment using PEG, but unfortunately the conservator passed away and the PEG solution appears to have been allowed to dry out. I've not come across wood midway through treatment like this before and I'd like to get some opinions on the best way to treat it.My thoughts are that the wood has now been allowed to dry out, so the best option would be to leave it dry and remove the majority of the excess PEG mechanically, followed by using some limited warm water on the surface to remove the last of it. The other option would be to think about resubmerging it and aiming to complete the treatment by freeze-drying it, but this doesn't seem like a good option to me because a) I don't know the concentration or weights of PEG which have been used so far, b) subjecting the wood to multiple wetting and drying cycles seems like it would be more harmful.Any thoughts and opinions on the best way forward? Is the wood likely to remain stable in ambient conditions now it has already dried out?Best wishes and thanks in advance. ------------------------------ Thomas Wicks Conservator Salisbury United Kingdom ------------------------------ You are subscribed to "Global Conservation Forum (ConsDistList)" as [email protected].
