<div class="moz-cite-prefix">Hi Tom,<br>
<br>
the problem with the Copenhagen lids supposedly is the denaturing
agent that is used in Europe: it is a very aggressive Ketone
(methylethylketone or MEK); might be worth to check this on your
order forms of your supplier or on your ethanol containers.
Copenhagen jars do better in collections using camphor as
denaturant though (Belgium and France).<br>
Same here in Munich, al lot of cracking and I am disposing all
those jars of; might be worth to opt for standardised metal
twist-off lids or pharmaceutical jars (clear glass quality, PP
lids with PE-inlays). First lids are used in our collections and
Stockholm since many years with good results (and because lids and
jars have standardised neck easy to replace in case of failure).
Second type was introduced in our collection more then 10 years
ago with good results; replaced on this occasion old backelite
lids.<br>
<br>
Have been testing Andy's jars since some time now (on the window
sill with indirect sun exposure) with good results, but as Andy
knows, I am also sceptical if these labels will survive decades of
storage in MEK alcohol.<br>
<br>
All the best<br>
Dirk<br>

Andy, I thought you would say that, but the problem is your
own words below. “…longevity…” and “...that will stand the
test of time…”. We know that carbon pigmented ink on good
quality archival paper has done this. We don’t know yet what
polyester will do. You may well be proven right in time, but
other examples scare. Our Copenhagen 75 g glass jars have
good quality plastic lids that back in the 1960’es were
thought to be able to last for eternity. After more than
half a century they have started to crack, and we have
thousands and thousands of them…<o:p></o:p></span></p>

<p class="MsoNormal">To me, this seems like a lot of additional
effort (not to mention the fact that this technology is on its
way out and ever harder to maintain) to produce labels that
are inferior in both quality and longevity to those produced
by thermal transfer printing on spin bound polyester media.
The initial monetary investment may be greater but the reward
in terms of Museum quality labels that will stand the test of
time far exceeds this.
