As of early June, new Mount Cor products will all have acid-free properties.
This is an honest question; why do we need AF Mount Cor or anything that is an AF backing if it is being permanently heat mounted?
Sort of like a new type of oxymoron, right?
i think it's very useful. we use it almost every day. I know as framers we tend to get hung up on the "right way" to do everything, but sometimes a permanent solution is necessary. What's so bad about a permanent mounting solution that doesn't contribute to the decay of the item being mounted?
That's a fair question, since Mount Cor is truly permanent and therefore unacceptable for preservation framing. The primary competitor, Kool Tack, is fully reversible without invasive chemicals or procedures, so it is considered to be preservation-worthy.
One possible answer could be that using all-acid-free materials in Mount Cor imposes less potential for chemical reactions with the materials comprising the mounted items, such as art media/paints/inks and substrates. So, Mount Cor would be less potentially destructive over time, although no less permanent and unacceptable for preservation.
Even so, there certainly is some benefit in working to extend the useful life of non-preservation framing.
Much in agreement with this. I love being able to mount with 130 degrees, as even 150 still seems to make a color difference sometimes.
If a full-strength-hold, completely reversible, preservation quality, 130 degree product ever shows up, it's going to be great. Until then, for its uses, this is an improvement.
