Stoneware-and-Silver Combined Jewelry

Joyería en Gres y Plata

Jewelry that sets fired stoneware (gres) segments, painted with geometric and figurative motifs, into hand-fabricated silver bezels, so that the ceramic inlay, like a small mosaic, is the centerpiece rather than an accent; its makers call stoneware and silver 'dos materiales nobles' (two noble materials). The documented family workshop of Marcelo Pallas and Liliana Testa has belonged to AUDA since 1993, sells at its Mercado de los Artesanos, has helped organize the IDEAS+ fair since its founding, has shown every year since 1997 at La Paloma, Rocha, and exhibits in Uruguay and Argentina with the Escala Humana collective.

Geographic Center
Not specifically detailed beyond general Uruguay in available sources; flagged for follow-up direct documentation of the workshop's physical location
Community / Ethnic Group
Uruguayan family artisan-jewelry community
Estimated Origin
The workshop has been a documented member of AUDA since 1993 and has exhibited annually at the La Paloma, Rocha craft fair since 1997, indicating a practice sustained since at least the early 1990s
Cultural Function
The workshop's own framing of stoneware and silver as 'dos materiales nobles' (two noble materials) positions the combination itself as a deliberate elevation of ceramic — often treated as a secondary or decorative material in jewelry — to equal status alongside silver, reflected in their sustained, decades-long commercialization of the combined technique both nationally and internationally
Primary Materials
Gres (stoneware, high-temperature ceramic), fired and painted with geometric and figurative motifs; silver, hand-fabricated into bezels and settings
Primary Tools
Ceramic firing and painting/glazing equipment; silver fabrication tools (soldering, bezel-setting implements)
Process Overview
Stoneware is fired at high temperature and painted with geometric and figurative motifs, then set into hand-fabricated silver bezels and settings by Marcelo Pallas and Liliana Testa, working as a family workshop; the pair explicitly frame ceramic and silver as 'dos materiales nobles,' combining them as jointly central rather than hierarchically primary-and-accent materials, and have sustained this practice through more than three decades of documented institutional participation, including membership in AUDA since 1993, co-organization of the IDEAS+ fair since its founding, and annual exhibition at Rocha's La Paloma craft fair since 1997.
Traditional Applications
Not specifically documented as tied to a prior inherited tradition; the workshop's practice is documented as an individually developed contemporary family artisanal career
Contemporary Applications
Collectible fine jewelry (rings, pendants) combining ceramic and silver, sold nationally and internationally through established craft-association and fair channels
Notable Practitioners
