There are aftermarket electronic "rustproofing" technologies claimed to prevent corrosion by "pushing" electrons into the car body, to limit the combination of oxygen and iron to form rust. The loss of electrons in paint is also claimed to be the cause of “paint oxidisation” and the electronic system is also supposed to protect the paint. [4]
Custom strainers or inner panelings that are fit to the painting and secured with screws, therefore offering strength to the painting and allowing hanging devices to be attached without damaging a painting. [24] Cradling – Cradling refers to the addition of wooden supports or frames on the back of paintings. These slats require flexibility to ...
Encaustic is a method of painting that involves dry pigments mixed with hot beeswax, then applied to the surface of a support such as wood or canvas. A completed painting is then finished by taking a source of heat to reheat the surface and fuse it together. Encaustic paintings do not require a varnish, are resistant to moisture, and do not yellow.
Rust converters are chemical solutions or primers that can be applied directly to an iron or iron alloy surface to convert iron oxides into a protective chemical barrier. These compounds interact with iron oxides, especially iron(III) oxide , converting them into an adherent black layer ( black oxide ) that is more resistant to moisture and ...
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.
Pickling is a metal surface treatment used to remove impurities, such as stains, inorganic contaminants, and rust or scale from ferrous metals, copper, precious metals and aluminum alloys. [1] A solution called pickle liquor , which usually contains acid , is used to remove the surface impurities.
