The expression “la troisième fois est la bonne” has positive relevance for Caviezel's three pottery collections of vases and vessels – Grono (2016), Soglio (2019), and Vella (2023). All three collections are eponymously named for Swiss locations meaningful to Caviezel, and all three were produced in collaboration with a historic Portuguese porcelain manufactory. Collectively they illustrate Caviezel's ever-evolving perspectives and concepts. Produced for her Museum für Gestaltung exhibition Caleidoscope, two sizes and colourways of Vella vases plus a large bowl were for sale in the museum's shop. Decorated with engobe and reactive glazes, Vella expresses exuberance thanks to sprays of colour and the brush strokes Cavizel added while they were on the wheel. The tubular vases riff on the exhibition title which is named after the tube-shaped toy whose mirrors and colours change with every twist of the tube, while the vases also reference calliope pipe organs which was the name Caviezel chose for her grand entrance work for the exhibition.
