i have some 17 century sermons that have a paper wrap that was glued with
lineco white neutral ph white glue the factory claims it is fully
reversible-i am sure it is pva --i want to detatch the covers and do it with
wheat paste as the value is reduced if not pasted into wraps. is this
possible to reverse some pva-about 6 months old-?
i - is there a special reason why hot hide glue is no longer used? I believe
>>the purists are still using it? Or am I 20 yhears behind the 8 ball.
