anoxic fumigation of art objects utilizing argon gas

Has many advantages:

An oxygen analyzer reading of 50 ppm

An oxygen analyzer reading of 50 ppm

  • it has been scientifically proven to eradicate insect life, in all of its stages.

  • it is harmless to most art objects.

  • it is safe for humans if handled correctly

  • it can be used to eradicate mold spores on sensitive art objects

  • a large variety of art, ethnographic and archival objects can be treated

  • envelopes of various sizes can be created to conform to the requirements of a specific object

  • large-scale art objects can be treated.

SPECIFICS: All of our treatments are performed by a furniture conservator who is a Professional Associate of the American Institute for Conservation, and adhere to the ethical guidelines of the organization. Oxygen levels are monitored periodically and a written log is kept. Treatments are performed in our temperature and humidity controlled, alarmed and sprinklered studio in Mana Contemporary, Jersey City, NJ. Treatments can also be performed throughout the United States, onsite at your residence or institution. In addition, Mana Contemporary has temporary rental spaces available for very large or sensitive art objects. These temporary spaces have the following characteristics:

  • 70 degrees (+or- 3 degrees)

  • 50 percent relative humidity (+ or - 3 percent)

  • 24 hour security 

  • Cameras, motion detectors, door breaks, audible alarms, etc

  • Alerts go directly to the police department

  • Concrete building

  • Pre-action fire suppression

  • Two fire departments within a three mile radius (closest is one mile)

EXCEPTIONS: two studies listed below outline certain potential risks for works of art using controlled atmosphere argon gas treatment: In one study a number of pigments, when not in a binder, will fade. In the second, Prussian blue, when identified in dyed historic textiles will temporarily fade, and then recover. Please consult the articles for specific details and conclusions.
