Thank you for the warm welcome, as well as the compliments, and your messages, m. I am German, and a retired electronics, electrical and mechanical engineer. All of these require that I be detailed. lol
For 40 years, I’ve been researching antique Central European enamel decorated glass, with emphasis on Fritz Heckert replicas of Renaissance and Baroque drinking vessels (,,im altdeutschem Stil” – EN, in the old German style), such as the Reichsadlerhumpen, and of which, I have a very substantial collection of vessels from that series, as well as many other Heckert pieces, mostly Römers.
To address the last item first, I am not aware that any such items were produced in India, in silver. India is known the world over for its brass work.
Now for the vase. Let me begin with, the iridizing process was discovered by the chemists at Petersdorfer Glashütte Fritz Heckert, prior to 1890. They were seeking a method to mimic the chemical change that Roman glass excavated on the island of Cypress underwent, after having been buried there for more than 2 millennia. The iridizing occurred as the result of the chemical reaction between the glass and the minerals in the surrounding soil.
That is why, after the discovery at the Heckert glassworks, the colour of Heckert vases are described as the color plus the word Cypern, which is German for Cypress. For example, Krystallcypern (a whitish colour), Goldcypern (gold), Azurcypern (blue, green), Bronzecypern (a goldish/greenish colour), or simply, Cypernglas, regardless of colour. Unless you can read/understand German, and have read all of the books on Heckert, the average English speaking collector would never know this.
Take a guess at what colour the subject vase is? Hint: it’s Goldcypern. The glass pattern looks very familiar, like it’s from the Heckert “Kairo-Serie”. Based on the finish. It looks to be by Josephinenhütte, with whom Heckert shared the process, and marketed directly, or made by Josephinenhütte and marketed by Heckert. I’d date the vase as 1890, or later. The finish on the VA vase, is Bronzecypern.
One of my many research projects is to catalog the glass patterns in the various Josephinenhütte pattern books, because many were also supplied to Heckert. I’m currently working on the Series 400 pattern book, with many more pattern books still to go. I will update should I find that particular pattern.
I haven’t spoken to Maria (The Guilded Curio) in years. I corrected her on various Heckert items within her collection, but it seems that she never implemented them. I have to disagree with the assessment of Neuwirth – I have seen many errors in his listings, and don’t even get me started on his outrageous prices – really over the top. Case in point: he recently listed a Pokal. Nothing about the listing is correct. Not his assumption about the decoration, or his assumption about the maker and where made. He truly disappoints me. Now, Uwe Wolf of Glas Wolf, who I’ve known for years, is the exact opposite. Ditto for Jan at Glas Kilian.
