There are two reasons to heat the wood. First is to ensure that the wood is dry. Depending what area of the country you are in, the wood needs to be about 5% or less. You can bake the wood prior to stabilizing it. Get the weight of the wood put it in an oven for a fairly long time checking the weight periodically until the weight doesn't change. Put the wood in a plastic bag to allow it to cool but not gain moisture. Then put the wood covered in Cactus Juice in a vacuum pot to remove the air from the wood cells, when the bubbles stop remove the vacuum and allow the Cactus Juice to soak into the wood. Then the wood is heated again to cure the resin.Never done any stabilizing or related. Curious as to why you would heat the wood later.
