Step 1: Examine the Mat
Inspecting your framed art is the first step to protect and preserve your work, however, it must be done with the proper materials. The most noticeable and dangerous problem with older mats is the acid level in the paper. You will be able to see a yellow line along the bevel of the mat cutout. This will cause a subsequent yellowing in the art work called acid burn. This can often be repaired by a conservator but each piece is unique. If you see yellowing, you should bring the framed work to be defit and examined. If your mat is acidic, we will recommend a rag mat that has a balanced pH level throughout and will not yellow over time or cause acid burn on your artwork.
