JOHN VANDEBROOKE: My name is John Vandebrooke and on behalf of Expert Village, I want you
to take a look at beginning encaustic painting. Out gassing is a problem that happens with
wax painting and what happens here is that as I said, you take your polishing rag and
you polish it and if you leave it for a long period of time maybe, even a year or so, you
might find that a bloom begins to appear on the wax. It will be like a ghosty bloom that
would show up and it would make the picture dull basically. Now, it's not a disaster because
all you have to do is take a polishing cloth and start all over again to polish it and
you'll remove the bloom, but it's something that you have to be concerned about as far
as putting it under glass. Now, here is a case where if it's under glass like this and
it doesn't have a mat around the image itself to push it away from the glass, there could
be out gassing that happens on the glass itself. And then you wouldn't be able to get at it
to polish it so if you're going to frame a piece, don't do it this way. Put a mat under
the glass and then your painting under the mat, which gives it just a little space so
it's not going to out gas right on the glass surface.
