How to preserve glass painting?

How can you preserve homemade watercolor paintings?

• I know if it's framed behind glass and out of direct sunlight, that helps. Is there anything else you can do to preserve the life of a watercolor painting?

• Answer:

  Before Framing: Place your painting between two pieces of acid-free paper to prevent damage from dust and dirt. Lay it flat and keep it out of the light. Store it in a cool, dry place. When painting a picture, use acid-free paper and high-quality paints. Paints should have a light fastness rating of 1 or 2. When purchasing original artwork, speak to the artist if possible. Ask about the type of paper and paint quality used for the painting. Framing: Frame your painting as soon as possible to protect it from dirt, dust and handling. Mat your painting using acid-free mat board. A mat allows air to circulate around the painting and prevents damage from moisture. Hinge mount your painting. Mounting your painting provides support and protects it from bending and warping. Frame your painting under ultraviolet (UV)-protective glass to protect it from fading. Seal the back of the picture frame with paper to keep dust and insects out. Hang your painting away from direct sunlight. Vacuum mounting is not recommended for quality artwork. This process permanently fuses the painting to the mat board, reducing the value of the piece. It is recommended for inexpensive posters only. It is worth the investment to have good quality art mounted, matted and framed by a licensed, professional framer. Do not place artwork directly against the framing glass. This will trap moisture and damage the painting.
