Aluminia Bowl, diameter 15 cm, height 5.5 cm. Hairline crack in top. Decoration number 506/314. 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.
