Used on [[sepia tone|sepia-toned]] prints, gold toners produce red tones. Kodak published formulas for several types of gold toners, which use gold as the chloride.<ref>[https://web.archive.org/web/20160817134815/http://www.kodak.com/global/en/professional/support/techPubs/g23/g23.pdf Toning black-and-white materials]. Kodak Technical Data/Reference sheet G-23, May 2006.</ref> * Gold is a good reflector of [[electromagnetic radiation]] such as [[infrared]] and [[visible spectrum|visible light]], as well as [[radio frequency|radio waves]]. It is used for the protective coatings on many artificial [[satellite]]s, in infrared protective faceplates in thermal-protection suits and astronauts' helmets, and in [[electronic warfare]] planes such as the [[EA-6B Prowler]]. * Gold is used as the reflective layer on some [[Gold CD|high-end CDs]]. * Automobiles may use gold for heat shielding. [[McLaren]] uses gold foil in the engine compartment of its [[McLaren F1|F1]] model.<ref>{{cite book |last1=Martin |first1=Keith |url=https://books.google.com/books?id=pUhMRLiHiY8C&pg=PA42 |title=1997 McLaren F1}}</ref> * Gold can be manufactured so thin that it appears semi-transparent. It is used in some aircraft cockpit windows for [[Deicing|de-icing]] or anti-icing by passing electricity through it. The heat produced by the resistance of the gold is enough to prevent ice from forming.<ref name="gbc215">{{Cite news |url=http://www.goldbulletin.org/assets/file/goldbulletin/downloads/Cooke_2_15.pdf |archive-url=https://web.archive.org/web/20110726122946/http://www.goldbulletin.org/assets/file/goldbulletin/downloads/Cooke_2_15.pdf |archive-date=26 July 2011 |title=The Demand for Gold by Industry |publisher=Gold bulletin |access-date=6 June 2009}}</ref> * Gold is attacked by and dissolves in alkaline solutions of potassium or sodium [[cyanide]], to form the salt gold cyanide—a technique that has been used in extracting metallic gold from ores in the [[cyanide process]]. Gold cyanide is the [[electrolyte]] used in commercial [[electroplating]] of gold onto base metals and [[electroforming]]. * Gold chloride ([[chloroauric acid]]) solutions are used to make colloidal gold by reduction with [[citrate]] or [[ascorbate]] [[ions]]. Gold chloride and gold oxide are used to make cranberry or red-colored glass, which, like [[colloid]]al gold suspensions, contains evenly sized spherical [[gold nanoparticle]]s.<ref>{{cite web |url=http://chemistry.about.com/cs/inorganic/a/aa032503a.htm |title=Colored glass chemistry |access-date=6 June 2009 |archive-date=13 February 2009 |archive-url=https://web.archive.org/web/20090213164051/http://chemistry.about.com/cs/inorganic/a/aa032503a.htm |url-status=dead }}</ref> * Gold, when dispersed in nanoparticles, can act as a [[Heterogeneous gold catalysis|heterogeneous catalyst]] of chemical reactions. * In recent years, gold has been used as a symbol of pride by the [[autism rights movement]], as its symbol Au could be seen as similar to the word "[[Autism spectrum disorder|autism]]".<ref>{{cite web |date=2 April 2021 |title=Why 'Going Gold' is important on Autism Acceptance Day. |url=https://edpsy.org.uk/blog/2021/why-going-gold-is-important-on-autism-acceptance-day-2nd-april/ |website=Edpsy}}</ref> Summary: Please note that all contributions to Christianpedia may be edited, altered, or removed by other contributors.
