PFG, Picture Framing God
Interesting observations in the thread re: unusual stain on a piece of art from a "proper" hinge.
The thread is a PERFECT example of why there is a recertification class for the CPF exam and that the MCPF requires continuing education units for maintenance. Even if you don't take the exam (or pass) - the information studied can help to keep current on proper framing techniques and materials.
Back in the olden days when I started framing, adding a fungicide to hinging paste was a GAP (generally accepted practice.). I would venture to say that using starch paste and Japanese paper for hinging was an "advanced" technique and adding the fungicide was state of the art. Interesting that fungicide is frowned upon today and is no longer recommended as we have pieces that were framed using that technique that show delitortious signs.
Around the same time, we were also cutting holes in dust covers to allow canvas to "breathe" and an "advanced" technique was to line the holes with window screening to keep the bugs out.
And about the same time, 3M micro pore tape was recommended as an alternative hinging media. I still see it in some framing supply catalogs - and I bet it isn't there for cuts and scrapes.......
That is why going to educational venues (either chapter events or trade shows), reading trade magazines and other publications (including internet forums - though one must vet the source of the post/information) and belonging to a trade association is so important.
