Tim JamesI used to be a framer(10 years with my brother)and we were certified.I'm not as qualified as you guys as a collector,but I've learned alot from everybody here over the last year or so,I'm just glad that I can contribute something on a subject that I am considered some what of an expert.When it comes to framing materials,you actually have "acid free" and "PH neutral" at the same time.There are matbaords that are discribed as acid free,but they are buffered with calcium carbonate to neutralize the wood pulp.Rag mats don't go through this process .I just want everyone to know the difference.
