What is Crucible?
[[File:Crucibles.jpg|thumb]] In [[chemistry]], a '''crucible''' is a kind of laboratory equipment that is usually a small cup, about the size of a shot glass, made of porcelain or non-reactive metal. Crucibles are used to heat [[chemical compound]]s to very high temperatures using a gas burner. One of the earliest uses of [[platinum]] was as a material in crucibles. Metals such as [[nickel]] and [[zirconium]] are also used as a modern crucible material. ==References== * [http://www.b-jenterprises.com/AboutUs.htm Metal Technology - a manufacturer of crucibles] {{Webarchive|url=https://web.archive.org/web/20040404224310/http://b-jenterprises.com/AboutUs.htm |date=2004-04-04 }} {{LaboratoryEquipment}} [[Category:Laboratory equipment]]
