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 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 panther be deep enough to pic 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 panther window mat. This type of stain permanently weakens the paper fibers and is not easily removed or lightened in conservation treatment.

Once a wooden sculpture pic has been dehydrated cracks will appear, where even exposure to high relative humidity will not panther make the cracks close up entirely. pic However, conservators can fill the cracks with a variety of materials to create panther and pic a unified visual impression. What should I ask for when matting and framing works of art on paper? Mat board should be made from 100% rag or lignin-free cellulose. Sometimes those labelled as "museum board" or "conservation board" are not of the highest quality. Alkaline buffered boards are not sufficient if the board contains wood pulp. Photographs should not be matted panther with alkaline buffered boards as some prints are adversely effected by alkalinity. Hinges are used to attach the work of art to the backboard of the mat. They should be made of Japanese paper, and pic should be adhered with wheat starch paste. Pressure sensitive adhesive panther tapes and pre-gummed tapes should not be pic used. Photographs are often panther attached to the mat with photo corners.

How can I protect my works on paper from light damage? Even though your artwork may be framed under UV filtering acrylic sheeting, the intensity of the pic light and duration of exposure is a concern. Try to avoid direct and excessive daylight. Close window curtains or drape the artwork when possible. Windows panther can also be covered with a film or a screen that will lower light intensity and ultraviolet rays. If possible take down the artwork periodically and exchange it with another piece, allowing the work to "rest" in storage. The most light-sensitive materials include watercolors and gouache, modern color inks, pastels, newsprint and all color papers. It is important to remember that light damage is cumulative and irreversible.. My solid wood sculpture is cracking pic in the vertical direction. What can I do?Q. I have an outdoor bronze sculpture.
