This was only allowed to be used at court dinners when the emperor was present, and its technique was a well-kept secret that was only handed down by word of mouth to selected individuals.

That Empress Elisabeth had her own typically personal taste in tableware can be seen in
the earthenware service she chose for her private dairy at Schönbrunn, as also in the set of silver cutlery with its dolphin motif for the Achilleion on Corfu and the two English services (Minton and Wedgwood) with unusual flower and animal motifs that she bought for Emperor Franz Joseph. When travelling on her yachts, Sisi made do with a plain silver-plated alpaca service, which was also decorated with a dolphin motif.
