Re: mould over gum

[Katharine Thayer <kthayer@pacifier.com>]

Alberto, I agree that what's needed to remove mold from hardened gum  
is probably not the same as what's needed to prevent mold from  
forming in gum solution.

I would try a dilute household chlorine bleach (VERY dilute, because  
strong household bleach will dissolve the hardened gum).  The bleach  
shouldn't affect the color of the image, because the color is  
embedded within the gum.  (I was going to point you to a page where  
I've dropped a drop of full-strength bleach on hardened gum, which  
obviously dissolved some of the gum but didn't change the color, but  
I realize that that's a page that hasn't been uploaded).

It makes me a little nervous to suggest this; it would be best if  
there's a border of hardened gum outside the image area to test it on  
before using it on the image area.  But I do know that bleach is good  
for removing mold from all kinds of things.  Good luck,
Katharine
