Dear Ivo, metal: I knew, that was why I named it. Ikora was a trade mark and not only multilayered glass.
Guess we shall have to wait for vol. III of
Burschel/Scheiffele Ikora
lampsBelieve it or not, I bought this lamp from Jan Kilian as Ikora Unica
It could perhaps be made at Glasfachschule Prof. ?Eiff?, Stuttgart who made a joint Stiftung with WMF in 1921 - followed by WMF's NKA
Neue Kunstgewerbe Abteilung
Vol. 1 of Burschel/Scheiffele also shows an etched vase named Ikora without several layers of glass ... :roll:
Some more Ikora people here on the board who could help further :?:
Thank you!
