Bronze is an artdecoparis alloy of copper with other metals that modify its hardness, color, and ability to be cast into a detailed mold. When bronze is cast it is usually a gold color. After the casting and finishing artdecoparis is completed, the surface is often treated with chemicals and heat which patinates the metal, coloring it green, brown, black, or artdecoparis a combination of the colors. Foundries usually apply waxes or other coatings to the surface of a patinated outdoor bronze to protect it from pollutants. This wax may wear off in time. We recommend annual maintenance by a professional conservator. The surface of the sculpture may be washed to remove pollutants and dirt, and waxed. If done annually, the rate of corrosion will be retarded (though not totally eliminated), and disfiguring rain streaks will be minimized. I collect twentieth-century furniture. How can I best preserve it? Some twentieth-century furniture was created from non-traditional materials, such as foam, plastic, and cardboard.

Innocence 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, artdecoparis Robert Gober, 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 connecting 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.

Once a wooden sculpture has been dehydrated cracks will appear, where even exposure to high relative humidity will not make the cracks close up entirely. However, conservators can fill the cracks with a variety of materials to create 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 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 should be adhered with wheat starch paste. Pressure sensitive adhesive tapes and pre-gummed tapes artdecoparis should not be used. Photographs are often attached to the mat with photo corners.
