A pair of Loetz 'Alpenroth' vases

In a survey about the World Expo at Chicago in 1893, the German Centralblatt, Vol.9, 1894, P.481 reported on the new Loetz colour combinations 'Alpenroth and Alpengruen, red opaque or yellow-green deminished colours, respectively, over a base of skyblue glass'. My mirror pair of 'Alpenroth' vases are decorated by a flying heron within flowering branches with attached red and yellow 'jewels' according to the upcoming 'Japonism' taste of Art Nouveau. In contrast, the brass mount shows a combation of 'New Gothic, New Renaissance and New Baroque' motives, being popular in the late Victorian period. The vases stand 19 cm high and have a diameter of 11 cm, or 14 cm including the mount handles. The production number is PN=I/4013 (1892). One vase is signed indistinctly in white by 'FSM' and clearly in golden ink 'I/170.a'. The latter numbering corresponds to the known Dek=I/107 of other 'Alpenroth and Alpengruen' vases, often differing by the type of birds within the jewelled branches.
