Aluminia was a Danish factory of earthenware pottery, established in Copenhagen in 1863. 
Philip Schou (1838-1922) was the founding owner of the Aluminia factory in Christianshavn. In 1882, the owners of Aluminia purchased the Royal Copenhagen porcelain factory. The factories were operated independently under their respective trade names until 1969, when the use of the Aluminia name was ended. Since then the products have been sold under the mark "Royal Copenhagen Denmark Fajance".
