Subject: Mold on paintings

Mold on paintings

From: Charlene Muscat <charlene_muscat>

I am a post graduate working in the conservation-restoration sector
here in Malta.  I came across this 20th century painting that is
infested by mold. On removal of the very thin recent varnish layer
the mold can be seen rooted in all the paint structure (probably due
to organic nature of the black pigment used by the artist--a
recurrent problem found on the black pigment in his works ). I am
removing the mold mechanically by scalpel under UV light and using
ethanol after to 'kill it'. Except from the usual RH/T control in
this case, I would like to ask if anyone knows of any
material/treatment that can prevent regrowth of mould (for example
anything that can be added to the varnish maybe). Note that this
painting is not very old canvas and pigment used are by their nature
very sensitive.
