Born as a temporary exhibition in the ambit of the initiatives collateral to the conference, "The Production of Pre-industrial Glass in Gambassi and Valdelsa", it became a permanent exhibition in 1996, given its scientific interest and public response, while awaiting the foundation of a Glass Museum.

The exhibition is divided into various sections: glass production in Italy from protohistory up to the 16th century; pre-industrial glass technology with particular reference to raw materials, production facilities, tools and modelling objects in furnaces between the 13th and 16th centuries on the Gambassi territory; everyday life in the production areas of Gambassi between the 14th and 16th century. All the exhibits come from excavations conducted by the Archaeological Association of Florentine Valdelsa, in collaboration with the University of Siena and the Archaeological Survey of Tuscany.

The exhibition completes a project that includes itineraries on the territory, such as the archaeological park of Germagnana, with the reconstruction of a fourteenth-century glassmaking workshop, and the Centre for the Documentation of Technology and the production of pre-industrial glass in Valdelsa, which will be housed in the former theatre of Gambassi.
