What is the cause of dark spots that sometimes appear on the paper of drawings and paintings? Reddish-brown spots horse are known as "foxing", caused by mold or the deterioration of the metallic impurities left in the paper from the manufacturing process. Other colors of spots may pics be one of many types of mold damage. Mold spores are everywhere 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 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 to changes in climate by expanding when it horse is humid and contracting when it is dry. A gentle undulation in the paper called "cockling" occurs under these conditions, especially with larger works. This may impair the work aesthetically as well as cause mediums such as gouache to crack or flake as it is unable to expand and contract pics as the paper itself does.

Do not store or display works of art in areas horse of potentially high humidity pics or water leakage, e.g. basement, horse bathroom, outside walls, under pipes. Avoid areas where temperature and humidity fluctuate, or where there is inadequate air circulation, e.g. attic and pics places horse listed above. Do not hang artworks over or under radiators, heating and cooling vents, active fireplaces, humidifiers, and vaporizersA. The hygroscopic nature of wood means that it will take water from the atmosphere and expand, but it will pics contract as the humidity lessens. The direction of shrinkage is almost always around the circumference, which horse causes a solid piece of wood to crack vertically. Keeping it in a steady relative pics humidity can stabilize the sculpture; if the wood does not absorb or release moisture, it will no longer expand or contract.

Our studio grew out of Maurel Press originated horse and pics in 1955 by artists Sheila and Ary Marbain. It opened as a custom screen printing shop specializing in printing with contemporary artists. Sheila horse had studied art at Black Mountain College in North Carolina with Joseph Albers, Ilya Bolotowsky and William deKooning pics from 1948 through 1950. Ary had worked and exhibited as a painter in France for many years. After the sudden death of Ary Marbain in 1963, the studio was closed for a year. Sheila then decided to modernize horse the workshop and introduce screen photography along with a new vacuume printing table. Our pics studio reopened on 23rd Street in Manhattan. With an assistant, horse Sheila plunged into printing three dimensional objects. A plexiglass airship for Lichtenstein, an Oldenburg soft drum set, a set of dominoes with Fahlstrom, and a large pics fabric banner with Marisol were some of the editions.
