The HP300 at the Computer History Museum has the same "mold" effects, as
does a 2648 I've got in my warehouse. HP CRTs (especially the elongated
ones found on the mentioned machines) seem to be more typically
susceptible to this effect than other CRTs. I wonder what it is about
them?

Are you
certain it was a mold eating at the sealant
Actually, there was no obvious mould as such on this one - it seemed
more like the sealant had turned to liquid in some places (visible as
'puddles' behind the glass), whilst in others it seemed to have
crystalised into small hard lumps (giving the visible white spots)
So, no sign of visible mould - I wonder if the dark spots sometimes seen
are maybe some form of optical effect; trapped bubbles as you say rather
than being something physically dark in colour.
