The Querandí glass company primarily produced artistic glass with a distinctive style.
From 1957 to 1976, Hubertus Ullmann transformed the family-owned Cristaleria Querandi S.A. into the leading colored glass factory in South America, fusing South American raw materials and minerals for the production of overlay colors.
It incorporated techniques such as blowing inside hollowed-out logs, resulting in organic shapes and particular textures.
They also employed the acid-etching technique, often with abstract or geometric designs, and in some cases, enameling.
The "sommerso" (submerged glass in layers of color) technique was used.
They manufactured for Ilum and commercialized their own artisanal line in Churba's stores.
