Sculptures

In the outdoor environment, the high concentrations of sulfur and nitrogen oxides from automotive and industrial emissions result in a corrosion having both soluble and insoluble corrosion products and no pacification. The results are clearly visible on outdoor bronze sculpture (see Airpollution Exhaust CONTROL, automotive Exhaust conthol, industrial). 

Physical Safety. Preventive conservation also involves ensuring the physical safety of objects (176). Objects should be guarded against acts of vandaHsm or damage inflicted by touching them. In many museums, greasy spots on sculpture can be seen, a result of repeated contact with bare hands.

Natural resins have been collected by hand throughout recorded history and used with minimal processing. They are reported to have been used in the arts, both in paints and for polishing sculptures, as early as 350 BC. Amber, the hardest of these resins, has been used as a gemstone from early Greek history to modem times. The electrical properties of amber were first recorded about 300 BC. Following is a description of commercial natural resins that are available in the United States. 

In many parts of the world, eg, China and northern Canada, block talc is used by the native artisans as a carving material and some of the sculptures produced ate widely treasured. Block talc is also used for manufacture of fireplaces in Finland and Vermont. Machined talc pencils have been used for marking steel during processing since the 1890s.

The sculpture shows artistically stacked tetrahedra. The molecular geometry for the molecule CCI4 is that of a tetrahedron. 

Still another use of EDTA is in the field of art restoration. Figure C shows before and after" photographs of Rodin s bronze sculpture The Thinker." This stood in front of the Philadelphia Rodin Museum for about 60 years prior to its restoration in 1992. Over time the sculpture had picked up a thick coating of insoluble CuS04 3Cu(OH)2(s). Application of a wet paste containing EDTA dissolved the coating by forming the soluble Cu(EDTA)2 complex. 

The glasslike sculpture is made of a polymer, which allows it to stand up to the outdoor weather. The repeating design, though random, recognizes the randomness and repetitiveness of the structure of polymers. 

Human respiratory functions may be impaired. Elevated levels of metals have been observed in some foods and drinking water in some locations. Masonry works, stone structures and heritage sculptures are subject to accelerated rates of erosion.

Over the eons, the flow and evaporation of water inside a cavern creates a stunning array of rock sculptures. Stalagmites grow upward from the floor, sometimes joining stalactites to form massive columns. Limestone dams create beautiful pools of water. Limestone draperies fall like curtains from water flowing around overhanging rock. Delicate mineral flowers sprout from the walls. All these features result from the aqueous solubility equilibrium of calcium carbonate.

In the studio Morgan s holding a small sculpture of burnished golden metal to the light from the window a series of roundels assembled at odd angles, so that they seem to shift and gleam, at once irresistible to my gaze and impossible to see.
