Aluminia Christmas Bowl. Beautifully decorated - also on the back. Measures 19 x 19 cm. Height 4 cm. In the 1880s when production at the Royal Copenhagen factory was dropping to a dangerously low level they were taken over by Aluminia (founded 1863), successful makers of earthenware, and since that time the two ranges, earthenware and porcelain, have been running in tandem.
