quote: Brad Miller Vitafilm in no way stops the vinegar syndrome process.
I have 8 3000ft reels of BEN HUR 4 trk mag IBTec that was soaked in Vitafilm and while there is only conjecture that it MAY have retarded the acidosis cascade, POSSIBLY extending the useful life of the print for maybe a year, the end result are reels of once gorgeous, mint film now needing a reciprocal saw to cut it off the reels, so badly decomposed is it that it can't even be unwound.
The thing about this destructive process is that there are many factors that affect its progression, although, as Monte points out, the end result is always that the print can no longer be run thru a projector. The reels of this particular print all deteriorated at different rates, even though they were kept in ideal conditions and separated from each other; some outlasting others by a year or more, but in the end, all are gone. Then by that same token, I have IBTec prints (Warner Brother cartoons all) which show no signs of acidosis at all and they are at least 60 years old. It's a mystery that chemists have not yet been able to come up with definitive reasons why some prints seem to be immune to the process and other succumb quickly. They never came up with a cure or are able even to explain that discrepancy, other than theorizing and certainly not been able to stop the process. As Paul says in HELP, "You've failed, scientist!"
