This is the annual bump
And thanks Rosie.
So far what I have appears to indicate a fairly earlish age to the decanter - my instinct says earlier than the 1930s (but I could be wrong):
- The glass to me looks quite old,
- It has an indented base and a snapped off pontil mark
- The dot technique was patented by H Wilkinson in 1905. CH British Glass 1800-1914 shows a bowl with 12 ribs with the same dot technique and references H Wilkinson's patent so appears to be indicating it dates to around 1905 and before 1914 if you take the date of the book (1800-1914) as a reference.
(Caveat - But technique also appears to have been used by other makers - evidence shown previously such as Regenhütte around that period, and in a link to an opaque glass flask in the National Trust collection undated but looks quite old, and this technique was also used definitely by Graystan in the 20s/30s, and I believe has been used more recently than the 1930s)
So another angle I been exploring goes back to Christine's mention of Cadmium and also the fact of the curious definitely orange
colour of the glass.
Could the orange glass in this vase be created by a combination of cadmium sulphide and selenium?
If that is the case then could it be that this must (might?) date to after 1892 when Franz Welz patented the orange coloured glass?
Ok that doesn't help be define the timeframe exactly, nor does it help on country or maker, but does at least give an earliest possible date for the piece.
Basically, I suppose I'm wondering if it is a sort of 'experimental' piece using a new glass colour and a 'new' dotting technique - which might pin it down to around 1900 (1905) for date?
I have absolutely no idea what country this might have originated from except possibly German for some reason.
