The conservation and restoration of copper and copper-alloy objects is the preservation and protection of objects of historical and personal value made from copper or copper alloy. When applied to items of cultural heritage, this activity is generally undertaken by a conservator-restorer.
Derveni krater, bronze, 350 BC, height: 90.5 cm (35 1 ⁄ 2 in.), Inv. B1, Archaeological Museum of Thessaloniki, after cleaning and conservation. Conservation and restoration of metals is the activity devoted to the protection and preservation of historical (religious, artistic, technical and ethnographic) and archaeological objects made partly or entirely of metal.
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.
Most metal objects are made from a combination of individual metals called alloys and exhibit different strengths and colors based on their composition. Metals and alloys commonly found in cultural objects include gold, silver, copper, pewter, tin, and iron. [14] The most common form of deterioration for metal is corrosion.
Once the metal objects become stable they can survive for some time underwater unless their environment changes [9] Pure gold will usually survive underwater for a long period of time without corroding. With silver objects, it will corrode quite easily, become very fragile, and form layers of concretion.
Restoration like preservation, it works to maintain as much of the original material as possible. However, the focus of restoration is to present the property at a specific point in history. As result repairs and recreations of certain elements or fixtures are completed and anything which postdates the intended period is documented and removed.
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.
Analysis and observation of collections objects when considering treatment and restoration occurs at all steps of the conservation process. Metal objects such as iron and steel share properties such as strength, conduction of heat and electricity, structure and more. It is important to understand the properties before conducting treatment.
