The transfer of acidity from one item to another due to direct contact or acidic vapors. A deacidification spray can be used on some acidic papers.
Occurs when paper comes in contact with acidic material or is exposed to atmospheric pollution.
The transfer of acid from one acidic material to another less acidic material, either by direct contact or by absorption of acidic gases from the surrounding atmosphere.
The transfer of acid from an acidic material to a less acidic or pH neutral material. This may occur directly, when two materials are in close contact.
The leaching of acid from one object to an object it is in contact with. The most common acid migration in scrapbooking is from your bare hands to your photos and paper.
The transfer of acid from an acidic material to a non-acidic material. This can happen even when the two materials are not quite touching. So when we say "use only acid-free materials," we mean it
Acid migration is the transfer of acid from an acidic surface to a non-acidic surface. Usually this is caused by adhesives, paints, inks, or storage systems that are acidic. Sometimes this can be caused by environment around non-acidic objects. For the rubber stamper, be sure to use acid free inks and dies when stamping, making sure that your projects will last for many years.
is the transfer of acidity from one item to another through physical contact or acidic vapours. If a newspaper clipping were put into an album, the area it touched would turn yellow or brown. A de-acidification spray can be used on acidic papers, or they can be colour photocopied onto acid-free papers.
Acid transferring from one material (usually more acidic) to another material (usually less acidic). This process has major implications in archiving works as it can cause discoloration of paintings and drawings, plus denaturing of supports.
Acid migration occurs when something with acid is placed against an article that is acid free. Photographs mounted on acidic paper will weaken and crumble. Acidic memorabilia can be added to photo albums if encapsulated in polypropylene sleeves or placed on buffered card on a page underneath a protective sleeve.
Transfer of acid from one acidic material to another less acidic material, either by direct contact or by absorption. If you don't wash your hands before scrapbooking, any acid or dirt on your hands can migrate to your scrapbooking supplies. Close Window
The transfer of acid from an acidic material to a less acidic or neutral-pH material. Occurs when neutral materials are exposed to atmospheric pollutants or when two paper materials come in contact. Acid can also migrate from adhesives, boards, endpapers, protective tissues, paper covers, acidic art supplies, and memorabilia.
This occurs when something with acid is placed against an article that is acid free. A deacidification spray can be used on some acidic papers. Warning: Photographs mounted on acidic paper will weaken and crumble. A work-around: acidic memorabilia can be added to photo albums if you encase them in polypropylene sleeves. An alternative is to place it on buffered card, underneath a protective sleeve.
Transfering of acid from an acidic material to a less acidic material. It can happen in your scrapbook, so be careful! Use sheet protectors and laminate those other items such as ticket stubs.
The transfer of acid from an acidic material to a less acidic, neutral, or alkaline material. This may occur when two materials are in direct contact or indirectly by vapour transfer. It can cause staining, weakening and embrittlement. The actual mechanisms of acid migration are not well understood, and the term is sometimes erroneously applied to any transfer of staining.
Acid can transfer from one item to another through close physical contact or even from contact with oils in human hands. Newsprint will cause paper to discolor, so any newspaper announcements or articles should be photocopied. Copy onto off-white paper for an authentic look.
The transfer of acid from an acidic material to one containing less or no acid. Also called acid transfer.
The movement of acid from one item to another that it is in contact with that has a higher pH, such as from a mount, mat or a backing to the work of art on paper to which it is attached.
