right like the subject
but i guess that was the only one discussed


That's probably air coming out. A friend who uses epoxy to impregnate
wood, puts the pot of mixed epoxy in a vacuum chamber for a while and
it foams up as the air bubbles, that were emplaced during mixing, are
forced out.

as pressure decreases boiling point goes lower so if it is volatile at
room temp it is more so as pressure decreases

but some could be air from mixing

I'm aware of that but in this case I think air coming out is dominant.

looking for some cross sections of stabilized pieces to see how far
resin penetrates


One of the presenters made knife handles and in the examples I saw,
penetration was at or close to 100% of the porous parts.
Incidentally, they also spoke of a much more environmentally and healthy
type of epoxy that is much less prone to give allergic reactions. I'll
give the name when I get the newsletter.
