A variety of plastic objects conserved in a museum (Finland) Conservation and restoration of objects made from plastics is work dedicated to the conservation of objects of historical and personal value made from plastics. When applied to cultural heritage, this activity is generally undertaken by a conservator-restorer.
Water causes damage and results from natural occurrences, technological hazards, or mechanical failures. Many cases of water damage can be traced to accidents or neglect. "A great many of the materials that museum objects are made of are highly susceptible to contact with water and can be severely damaged by even brief contact, while others may be exposed to water for longer periods without harm.
For example, when selecting a plastic with which to make storage enclosures, conservators prefer to use relatively long-lived plastics because they have better ageing properties - they are less likely to become yellow, leach plasticisers, or lose structural integrity and crumble (examples include polyethylene, polypropylene, and polyester ...
See Fiber-reinforced plastic.) [68] The resulting porous network is filled with monomer. When damage occurs in the material from regular use, the tubes also crack and the monomer is released into the cracks. Other tubes containing a hardening agent also crack and mix with the monomer, causing the crack to be healed. [63]
Restoration "focuses on the retention of materials from the most significant time in a property's history, while permitting the removal of materials from other periods." [4] Reconstruction, "establishes limited opportunities to re-create a non-surviving site, landscape, building, structure, or object in all new materials." [4]
The first step in developing a conservation-restoration plan is close examination to estimate the condition of both the panel and paint. This allows conservators to ascertain the full extent of damage and make a risk assessment. Techniques include visual observation and technically-assisted examination through diagnostic studies and analysis. [17]
The conservation and restoration of lacquerware prevents and mitigates deterioration or damage to objects made with lacquer. The two main types of lacquer are Asian, made with sap from the Urushi tree, and European, made with a variety of shellac and natural resins. Lacquer can be damaged by age, light, water, temperature, or damaged substrate.
The conservation and restoration of outdoor artworks is the activity dedicated to the preservation and protection of artworks that are exhibited or permanently installed outside. These works may be made of wood , stone , ceramic material , plastic , bronze , copper , or any other number of materials and may or may not be painted.
