Electrochemical techniques are used in conservation to identify metals or corrosion products, or to monitor or treat metal objects. Although there are many published reports on these techniques, [...]

Electrochemical techniques can be used to characterize corrosion on a metal object and to reduce the corrosion either to a different compound or back to the metallic state. These techniques [...]

A stabilizing wax formulation is proposed as an alternative to lacquers for protecting copper, brass and bronze against atmospheric corrosion and tarnishing. This special wax is based on [...]

The paper illustrates the usefulness of technical information in firming up a difficult chronology. The results of the semi-quantitative X-ray fluorescence analysis of worn coins allowed the [...]

An ancient Chinese kuei bronze vessel attributed to the Middle Western Zhou period was examined by X-radiography. Important information regarding its method of manufacture and composition was [...]

The conservation treatment of an 18th-century fire appliance is described after a brief history of its origin. The treatment of the corroded iron, bronze and copper parts, and various accessories [...]

This paper reviews various field-tested methods for cleaning machinery and treating surface rust as preparation for display. The treatments combine the use of traditional conservation methods [...]

The display, storage and cleaning of historical silver is discussed in detail along with silver tarnish and its cause. Recommended storage includes wrapping silver in good-quality tissue paper [...]

Freshly excavated archaeological iron was stored in deoxygenated aqueous solutions using chemical oxygen scavengers. The most promising results were obtained using sodium sulfite though the [...]

Nine commercial rust converters and tannic acid were evaluated for their ability to form stable coatings on corroded iron artifacts stored or displayed outdoors. The rust converters were analyzed [...]
