Cristalería Querandí S.A. was a leading South American art glass factory active from the 1950s through the 1970s. This piece is made in Annagelb, a rare yellow glass developed by German glassmaker Otto Ullmann. After emigrating to Argentina in 1950, Otto became the technical manager of Bohemia Glass Argentina and later helped establish Querandí as a major producer of colorful studio glass.
Hubertus Ullmann evolved the family owned factory Cristaleria Querandi S.A. to the leading color glass factory in South America after his resettlement to Buenos Aires in 1957. He tested the neutralization in glass of radioactive waste for the Argentinean Nuclear State Direction, producing the distinctive Annagelb by using Yellow Cake instead of uranium oxide.
