CONSERVATION PAPERS<br />

photographic storage papers<br />

100% Cotton, Unbuffered, High Purity, Silver Image Safe Papers and Photographic Storage Products this range consists of papers made from<br />

pure cotton inters containing no chemicals whatsoever and because of this they are probably the purest of all photographic storage papers.<br />

They are uncalendered to allow maximum air flow and prevent any potentially harmful build up of gases that may be emitted by thephotographic<br />

material stored within the enclosure. Due to their purity and porosity, these papers can safely be used for long term storage of all kinds of<br />

photographic materials be they negatives or prints and irrespective of the photographic technique used to create them.<br />

Although primarily geared towards the storage of photographic material, the paper is equally well suited for storage of a multitude of other<br />

museum and archival treasures, such as textiles, historic documents, stamps, coins and archaeological objects or any other item requiring a high<br />

purity non alkaline environment.<br />
