I have to say that I was one of the first with by bowl out when white-cored/acid-free/conservation/whatever
mountboard came on the market. There was a great raising of awareness on conservation techniques from the early
'80s onwards. Prior to that, most jobbing framers would not really pay heed to conservation aspects. Some still don't.
But.... The wheel has rolled a bit too far in many cases, whereby people will agonise over things that don't really matter
while ignoring important things that do matter a lot.
I don't want to get into a slanging match on this but one thing that bugs me is backing boards. Some folks (who shall remain
nameless) insist on using card backing board. OK, MDF is not perfect but used with a polyethylene membrane it's the ideal
backer**. The card stuff (IMHO) is far too flimsy. The corrugated stuff offers little to no physical protection. Same with foamcore.
But as it is sold with conservation or acid-free tags folks lap it up. It may have all the conservation credentials but if something gets
jammed in the back all the Ph ratings count for nothing. You art is knackered in a second. MDF will absorb a lot more abuse.
I sometimes get the impression that some folks (customers and framers) regard conservation materials as somehow having an
active effect. Put something acid-free near your art and it will somehow preserve it. It has no active effect. If a framed item
carries the seeds of it's own destruction then no amount of conservation materials/techniques will prevent it ultimately going
manky. Might slow it down a tad...
** I'm talking backing boards here. NOT undermounts.
