Editing Graphite (section)

===Foundry facings and lubricants===
A foundry-facing mold wash is a water-based paint of amorphous or fine flake graphite. Painting the inside of a mold with it and letting it dry leaves a fine graphite coat that will ease the separation of the object cast after the hot metal has cooled. Graphite [[lubricants]] are specialty items for use at very high or very low temperatures, as forging die lubricant, an antiseize agent, a gear lubricant for mining machinery, and to lubricate locks. Having low-grit graphite, or even better, no-grit graphite (ultra high purity), is highly desirable. It can be used as a dry powder, in water or oil, or as colloidal graphite (a permanent suspension in a liquid). An estimate based on [[USGS]] graphite consumption statistics indicates that 2,200 tonnes were used in this fashion in 2005.<ref name=usgs/>  Metal can also be impregnated into graphite to create a self-lubricating alloy for application in extreme conditions, such as bearings for machines exposed to high or low temperatures.<ref>{{Cite web|url=https://www.foundrymag.com/feature/graphitemetal-alloy-extends-material-life-high-temperature-processes|title=Graphite/Metal Alloy Extends Material Life in High-Temperature Processes|date=2004-06-04|website=Foundry Management & Technology|access-date=2019-06-20}}</ref>
