CM-U: In terms of treatment, we have done some, but very – you know, not very much.
CM-U: In Washington, we talked a little bit about the paper and the manipulation of it. And you talked about folding…
Jasper Johns: Yes, it's made of little rectangles of paper that
were folded, and then torn, and opened, and attached – I was looking at
the back of it. I don't know how they were attached. I thought they
had been attached with enamel or something, but there's no sign of that
on the – there (points finger at painting's verso).
CM-U: Yeah.
Jasper Johns: So perhaps they were just glued down. I don't
know. But I think the paper was then covered with white. A white
enamel, or perhaps a white oil paint. But I imagine a cheap, canned
enamel. And then sort of glazed with this viridian.
CM-U: Um-hum. When I was in – when we spoke about this last
time, I was asking you – it has come down through the records as oil on
canvas…
Jasper Johns: Um-hum.
CM-U: …and it certainly has a translucency of enamel, you know,
or oil, or whatever. But I was asking you about wax. And I remember
your saying that, you know, your recollection was that it certainly was
enamel or oil. The reason why I was asking you about wax was that, in
1990, in January of 1990, we had a cold snap and a problem with the
system for a very short time, and the picture developed white crystals
on the top of it. And the crystals were specific to the darker areas.
Jasper Johns: Uh-huh.
CM-U: They were very easy to just be brushed off, but I did take a sample and had it analyzed.
Jasper Johns: Uh-huh.
CM-U: And it came back – the results came back as being a type of
stearic acid that would be predominantly found in a wax material. And
we thought – Liz [Elizabeth Lunning, Conservator of Works of Art on
Paper, The Menil Collection] and I looked at this, and thought that was
very odd, given the kind of translucency of the medium and other aspects
of it. But just the other day when I was looking at it again, and
thinking again about this report, I was wondering if maybe, since the
whiting was primarily on these darker areas…
Jasper Johns: Um-hum.
CM-U: …that maybe there might have been some element of that. Do you have any recollection of that?
Jasper Johns: I don't believe.
CM-U: Don't…
Jasper Johns: I don't have any recollection. That's for sure. And I don't think that I added wax to it.
CM-U: Okay.
Jasper Johns: Uh…
CM-U: Well, that's fine. I mean, then that continues to be
something that we investigate. Because it could also be related to
linseed oil, perhaps.
Jasper Johns: Um-hum. I don't know what medium I used, you know, to thin the oil with.
CM-U: Um-hum.
Jasper Johns: I don't remember.
CM-U: Well, it's not a serious problem. I mean, it's something
that's very surface-oriented, and it doesn't seem to detract, you know.
