Mike , a quick search in the general bargains sticky produced a thread from a member named Jon Kennedy. His email is
bones@plainstatesenergy.com. In a post he said he's been stabilizing wood and other stuff for about 5years. The post I saw was posted in -April of last year.
I have seen a guy advertising clear glass stabilizing chambers for sale in two sizes. I couldn't find the add on here, but you might be able to google search 'glass stabilizing chambers' and find the add.
Good luck! I'd love to test some for you-!
I've been looking for burl every time I go in the woods, no luck so far. If I find any maybe I'll send it to ya!
