Polyethylene Glycol PEG Green Wood Stabilizer
Use to stabilize green wood to keep it from cracking, splitting and shrinking. Wood treated with Polyethylene Glycol (PEG) is ready for carving, shaping or machining.
Polyethylene Glycol is dissolved in water. Wood is treated by submersing into the PEG/ water mix. 10 lb. container (10 lbs. will make 15.4 quarts of a 30 percent solution or 8.48 quarts of a 50 percent solution).

Personally, I found the tables to not be very relevant. The PEG solution is expensive to mix in any volume so I rough turn the pieces to 2-3" wall thickness and place the piece in a poly bag with a 25% to 30% solution. Silver maple, mimosa, red oak and hackberry have taken several weeks. Plan on at least a couple of months. the treated wood is great to turn but it is messy. I wear goggles and rain gear.
The limitation, from my experience, is that the PEG solution will only penetrate a few inches. The wood inside the PEG absorbed layer is wet but not stabilized. It could develop cracks. I treat large blanks for turning by placing the rough turned pieces in a 20-25% PEG 1000 solution for 10 - 14 months. When I remove the piece from the solution, it is very easy to work. It takes a few weeks to dry. Since I remove the interior wood, the limited penetration is not a problem.
I don't believe there is much you can /should do to a log other than treat the end grains
Is there a way to test this? Maybe use some kind of chemical substance for testing or some kind of machine.
