The Royal Pottery Factory in Rato in Lisbon, founded in 1767 at the initiative of the Marquis of Pombal, was one of the factories of the core industries and applied arts that arose in Lisbon in the neighbourhood of Rato. During the first phase of its operation from 1767 to 1771, the factory was run by the Italian Tomás Brunetto, who was succeeded by the Portuguese master potter Sebastião Inácio de Almeida until 1779, when the factory fell into almost complete disuse.
