Hi, Cathy. The Science Museum of Minnesota has a huge tree cookie, so they might have some advice. You could also try the Laboratory of Tree-Ring Research at the University of Arizona. My brother took a college class that referenced that lab's research, and he said it was pretty fascinating.

Good luck!

Cathy,

I am not a conservation expert, but archaeological waterlogged wood remains are often treated with PolyEthylene Glycol (PEG) or other chemical solutions to preserve them (seen at ship museums like the Mary Rose or the Vasa, and my own personal experience as a student at the York Archaeological Trust). I've volunteered in a museum which exhibited a large cross section, over 4 feet in diameter, and it appeared to be coated with polyeurythane (?) or other clear wood stain/preservative. I'm not officially recommending either of these solutions, just wanted to share what I've seen. If you can afford a consulting fee, you might want to put out an RFP for analysis, exhibit design, or conservation to get professional advice!

Good luck finding a solution!

Dear Cathy,
 
My husband is a forester and was intrigued when I shared this question. He recommends that you contact the Minnesota Industrial Forestry Association. He is confident that they will be able to direct you on such processes.
 
Good luck!

Hi everyone,
 
Is there anyone with experience preserving a cross section of a tree in their collection? Our town has just cut down a very old, "historic" tree and there are some who are beginning to look at our historical society as the place to preserve a cross section taken from the stump. Adding something organic to the collection takes some thought as does adding anything with great size into our small storage area. I'd like to be knowledgeable about the reality of preserving something like this should we get offered a section of the tree. Does anyone have experience to share?  
 
Thanks!
