Where
Where it is practised in Tuscany
The hands that practise it have a clear capital: Impruneta, in the province of Firenze, and its hill territory. Here the clay — rich in galestro and poor in carbonates — is the best in Italy for high-temperature firing, and it produces an object resistant to frost that has clad the floors of the Medici villas, the pots of the Boboli gardens and the roofs of half of Renaissance Firenze. The Terracotta dell'Impruneta denomination has institutional protection, and the historic kilns still in operation have often been working for four or five generations. It is also practised in the Siena area (around Petroio, where the potter is an old popular tradition) and in limited areas of the Pisa and Pistoia countryside, where local clay fed domestic production.
