Acid -  Is a word used to describe a property of some materials that makes materials around degrade, slowly or quickly, overtime. This, scientifically speaking, is marked by the material giving off a certain type of microscopic particle when put in water or H2O - more specifically a positively charged Hydrogen ion (H+). If you don’t know what that means it’s basically that this when this stuff touches other stuff it destroys it. With stomach acid it digests food within minutes or hours; with low quality and NOT acid-free framing materials it slowly breaks down the artwork over years.
Acid Burn -  These are the yellowish-brownish marks and lines that can appear on artwork that are caused by low quality or non-acid-free framing tape or the general yellowish-brownish tinge that can appear on artwork over time from not being framed using conservation materials. Non-acid-free materials can cause artwork to discolor in different ways and become brittle over time.
Acid Free -  Acid free framing materials are pH neutral and will not emit harmful chemicals that may damage your artwork over time. See Archival and Conservation Framing.
Acid-Free Mats -  The mats called acid-free have been purified to neutralize the acidity. Although this is good, this type of mat is not a substitute for rag or alpha-cellulose mats when you want to adhere to conservation standards.
Acrylic -  Acrylic is an alternative instead of glass. It doesn’t break as easily and is somewhat lighter in weight, especially in larger sizes. People often say Plexiglas when they should say acrylic. Plexiglas is a brand name.
Allowance -  When frames are made, they are cut slightly larger than the size desired. This provides space so anything that is the actual size will drop into the frame.
Anti-Reflective Glass -  A type of coated glass that greatly reduces reflection without distorting the art behind it.
