I couldn't find this information anywhere on the board, so I apologise if it is already here.
I have been looking at possible decorators for a Gordiola glass plate I own that is signed Gordiola. I have also been wondering about the date.
Having read the various discussions on enamellers linked to Gordiola Glass in various ways, I have been trying to investigate Cirera (and Royo ).
I came across this information in this book (see link)
If you click on the link there is a black and white picture of a Cirera enamelled piece in the book - called the St George cup dated as 1947-1950.
The decoration looks like the decoration seen on various pieces on the board signed Cirera, however I cannot see a signature on the piece in the book to compare.
I do not know where the cup in question was made, and the piece does not give that information.
The dates mentioned for Genis Cirera Casanovas work seem to span 1928 to 1960 as it says he won the Bilbao Decorative Arts prize in 1928, as well as numerous mentions for the 1940's and then into the 1950's including one in Madrid in 1953 and says his production lasted until 1960.
It mentions that his workshop then continued for longer run by his daughter.
I used Google Translate to translate the information given but have ensured the award names of the places are as they were in the original as Google automatically tries to translate them into something else.
There is information on various decorators/enamellers of glass and Genis Cirera Casanovas is one of those described.

Its production lasted until 1960 but his workshop continued for much longer run by his daughter and his son, although industrially.'
There is a long list of enamellers of glass in the link.
Unfortunately some of the pages are missing.
However under where I would expect to find R for Royo, there was no Royo and neither was there any mention of Royo anywhere else in the list as far as I could see although as I said, there were missing pages so names would be missing I would think and Royo might not have appeared as the middle name therefore could be somewhere else in the list as it seemed to be alphabetical based on middle name.
