No sorry, I where at the time working at the institution and all the tests where made for a major Museum! The result is not my privately owned resource and it wasn’t meant to made for publication anywhere. But that was edges ago when papers like the Oriental and others where available. I think it was around 15 or some less papers served a basics to the tests. I can tell you that much that the final products where washed to archival status Ph tested for hypo and dried with air, and with tissue (slowly) and some of those where flattened with dry mounting seal in different temperature and time duration. Agfa and Oriental was those which where absolute the best (high above) compared to other major brand. Some of the brands had major cracks on the surface very ugly ones and lots of them! I will not name it those because I don’t want people jump on my back again and I’m not sure if I remember those in the right order either! Anyway it can not refer to today’s material at all at least that’s what I believe also many of those products are not available any longer or the basic chemistry of those whom still exits may had been changed!
I might just talk to our local hospital if I can borrow or if they have the right equipment for re-emerge this test in as privateer than of course if it’s possible than I would publish the results.
I thought that PE is already very close to everything and he might do the tests.
What I forgot to say is this, before we have conducted the tests investigated all the dry material and we fund that the surface had cracks even before the dry mounting seal it’s just increased more with the effect of the heat!
Also important to mention that, than we investigated the row material which we begin with and than we find out that cracks clearly shown but it's increased more step by step and it was different on each paper. Itell you some of the surface was really a nightmare!
