Amalgam (dentistry) and for large foundation restorations, or cores, which are precursors to placing crowns. The reaction between mercury and alloy when mixed together is termed an amalgamation reaction. It will result in the formation of a silver-grey workable mass which can be condensed into cavities. After condensing, the dental amalgam is carved to generate the required anatomical features and then hardens with time. In the pre-1986, the standard composition of alloy is referred to as conventional amalgam alloy. More recently (post-1986), there have been a change in the compositional standard of the alloy due to better understanding of structure-property relationships for
UCPH Department of Chemistry moved several times, usually to better surroundings. In 1962, Universitetets Kemiske Laboratorium moved to its present location in the H.C. Ørsted Institute (HCØ), named after Hans Christian Ørsted who discovered electromagnetism in 1820. It is less well known that H.C. Ørsted was also an able chemist, and that he was in fact the first person to isolate the element aluminium. UCPH Department of Chemistry The Department of Chemistry () is a department under the Faculty of Science, University of Copenhagen. It is the largest basic research institute in chemistry in Denmark, and is responsible for the teaching of chemistry at
