Glazing can be either glass or acrylic. Only glass should be used with any friable media such as unfixed pastels, charcoals, or graphite, never acrylic as it can damage the work by cartoonclipart attracting these materials. There are many brands of acrylic glazing to choose from; one with an ultraviolet filter is recommended. The frame and the mat should be deep enough to prevent the artwork from touching the glazing. A stiff backboard behind the mat protects and supports the matted artwork. It is best to use non-acidic boards. A dust seal with paper or tape is also recommended. What damage results from using poor quality mat board? Avoid mat boards containing wood pulp which causes "matburn"--a darkening of the paper under the mat or at the bevel cut of the window mat. This type of stain permanently weakens the paper fibers and is not easily removed or lightened in conservation treatment.
