Estanho de São João del Rei
The casting and finishing of estanho (pewter — an alloy of 90 to 98% tin, refined from cassiterite ore, combined with 1 to 8% antimony and 0.25 to 3% copper, since pure tin is too soft for standalone use) into liturgical and domestic objects with distinctive baroque and colonial design, centered in São João del Rei and neighboring Tiradentes, historic gold-cycle towns in Minas Gerais's Campos das Vertentes region. The craft traces to the Portuguese colonial period, when goldsmiths and silversmiths, whose gold and silver raw materials were confiscated under crown monopoly, turned to the next most available metal to sustain their livelihoods — a documented, specific case of colonial extraction policy directly redirecting artisan technique toward a substitute material. São João del Rei served as Brazil's center of tin mining until 1985, and the craft today holds formal Geographic Indication (Indicação de Procedência) protection, administered by the Associação dos Artesãos de Peças em Estanho (AAPE), whose members developed a formal quality regulation governing every stage of production required to earn the 'São João del Rei' seal — its logo drawing on the bell and the chalice, two objects understood as emblematic of the town and its craft.
Risk level: Vulnerable · Not Applicable — no UNESCO Intangible Cultural Heritage inscription exists for this craft at time of writing, though it holds formal Geographic Indication (Indicação de Procedência) legal protection specifically certifying the 'São João del Rei' origin and quality seal
