Reddish-brown spots are known as "foxing", caused by mold or the deterioration of the metallic impurities left in the paper from the manufacturing artist process. Other colors of spots may be one of portrait many types of mold damage. Mold spores are artist everywhere portrait in the environment, and mold thrives on cellulosic materials, especially in conditions of high humidity (above 65% of relative humidity). Keeping artworks out of high humidity areas like artist and portrait bathrooms or exterior walls, can help reduce the development of such stains. If I have a work of art on paper that appears to not be flat, should I be concerned? Paper is hygroscopic, reacting artist to changes in climate by expanding when it is humid and contracting when it is dry. A gentle undulation in portrait the paper called "cockling" occurs under these conditions, especially with larger works. This may artist impair the work aesthetically as well as cause mediums such as gouache to crack or flake as it is unable portrait to expand and contract as the paper itself artist does. Innocence portrait and Experience deals principally with the shift in recent decades from a positive, hopeful vision of childhood’s purity and power to a counter-imagery of youth threatened or corrupted. The gallery exhibition includes works by Diane Arbus, Robert Gober, artist Mona Hatoum, and Mike Kelley. An accompanying film and video exhibition includes films and videos by Stan Brakhage, Joseph Cornell, Sadie Benning, Louis Malle, Satyajit Ray, and Arturo Ripstein. Matter investigates the new role of materials in fine arts and design, as well as its force in inspiring and guiding the creative process, by considering and portrait connecting artist several distinct creative fields. Works by Joseph Beuys, Robert Morris, Gaetano Pesce, Mona Hatoum, Eva Hesse, designers Hella Jongerius and Tom Dixon, and photographer Vik Muniz are shown. Glazing portrait 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 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 artist the paper fibers and is not easily removed or lightened in conservation treatment. | ||||||
