300º post our best Argentinian glass vase, another Querandi

Several years ago I posted another Querandi glass, the link down in commentaries.
I have been thinking what to post celebrating number 300 and I decided to share this magnificent glass done in my country. It is heavy about 1,250 grams, the color is like pure water like the textures. It measures about 20 cm. It is signed Querandi the number of the mold and the year 1971. Very difficult to show the details. The first picture with flass, the second without. The third the mark and the fourth inside the vase.
Querandí is one of the groups of aborigines of the Santa Fe province in Argentine. This facility that has produced and exported art glass and lamps, the price here and abroad is high because it is searched by collectors. They are all of high quality.
From the web page of the firm Optul http://www.optul.de/en-home-milestone.php I copied the following;
1950 to 1954
Otto Ullmann becomes the technical manager of the glass factory Bohemia Glass Argentina SRL in Santo Tomé after his emigration to Argentina. Otto and Hubertus Ullmann test together in numerous sample melts of South American raw material and minerals for the production of massive and overlay coloured glasses.
1957 to 1976
Hubertus Ullmann evolves the family owned factory Cristaleria Querandi S.A. to the leading colour glass factory in South America after his resettlement to Buenos Aires. Among other things he tested the neutralization in glass of radioactive waste for the Argentinean Nuclear State Direction. He produces the well known Annagelb by using Yellow Cake instead of uranium oxide, at the same time he invents two new Yellow Cake colours Rosanil and Braunil.
1978 to 1982
Hubertus Ullmann remigrates to Germany and is now owner of the Hubertushütte located in Osterhofen. Beside the main production of high- and full-lead crystal, coloured solder glasses for insulating vacuum proof electric feedthroughs. Changing market dynamics and tightened environmental regulations are forcing him to close the glass factory.
The facility closed without paying the indemnization to the employees in 1992. Then in 1994 it was open again by Gustavo Viau a cineast that had worked in Highlander II: The Quickening filmed in Buenos Aires during 1991 that had to find a special sphere of crystal that Sean Connery had to break, The facility was open till 1994.
One of the main designers during the sixties were Alberto Churba http://www.fundacionkonex.com.ar/b54-lI-Alberto-Churba, Víctor Carroza http://www.miriamchandler.com/descargas/articulos/53.pdf, Rosendo Tellechea https://www.facebook.com/RosendoTellechea, Celina Castro http://www.fvsa.com/_ldi/LDI.pdf
