Most examples of what we currently call "cobalt ciselé" are cobalt oil spots on a "Diana" green ground. I think this is technically correct (personally, I would call them Diana with Cobalt ciselé), but since 1973 there has existed in the MAK (Museum of Applied Arts, Vienna) a collection of sample tiles from the Loetz factory. Some of these tiles are photographed in Loetz Austria 1900, by Waltraud Neuwirth. One of them has a paper label that denotes "cobalt ciselé" (see scan in third photo). The fourth photo scan is from Loetz Bohemian Glass, 1880-1940, Volume II (Ricke).
The finish on this tile matches that of my new vase. This is cobalt ciselé on a cobalt ground. The enameled decor closely resembles the Dek IV/714 I posted previously, but the flower on this one is slightly different.
