I am in need of interleaving paper to cover some of my prints on Juniper Baryta Rag and am looking at glassine rolls at Archival Methods. On their website they state:
"glassine should not be used with photographic negatives and prints as these photographic media have a protective gelatin layer. With high humidity and warm temperatures the gelatin layer can become soft and the smooth surface of the glassine can stick to the negative or print causing unwanted damage."

I know the coating on Baryta paper is barium sulfate, does that mean that Juniper Baryta is fine to use with glassine? Aka..that it does not contain any gelatin? I am located in the south so humidity is a problem down here.

Thanks

Hi Justin - Glassine is perfectly suitable to use with the Juniper paper. Although the Baryta coating is the same on both the silver halide and inkjet papers, there is no gelatin coating on Juniper to interfere with the glassine.
