We do not know the precise date when porcelain began to be manufactured at the Retiro. Clarke, writing in 1761, says the works had begun, and in 1764 pupils attended the classes at the Academy of S^{n} Fernando. Larruga, in his "Memorias," says that as soon as the building was finished, china was made under the superintendence of Don Cayetano Schepers; the works, during his superintendence, proved very unsatisfactory, to his great astonishment, as the same process and workmen were employed as at Naples. Schepers attributes it to squabbles between the Spanish and Italian workmen. Sebastian Schepers, from 1783, a son of Cayetano's, tried various experiments with different clays of the country. The porcelain made at Buen Retiro was kept for the first thirty years for the exclusive use of the royal family, or to be sent as presents to foreign courts. Nothing was offered for sale until January, 1789, after Charles III.'s death, 1788, when Charles IV. determined that the china manufactured at Buen Retiro might be sold. Even in Spain the specimens of this china are very scarce; it is only at the palaces of Madrid, Aranjuez, the Escorial and La Granja that an idea can be formed of the perfection of this manufacture. The director at that time was Don Domingo Bonicelli, a son of Don Juan Bonicelli. Don Domingo chose a room within the Retiro, which was arranged at a cost of £350, in which to exhibit the objects for sale. Another room was taken in the Calle del Turco, which is mentioned in "Noticias varias y curiosas de Madrid," Valero Chicarro, 1762-1793, which we find was closed in 1800, as the "objects manufactured at the Retiro were simply for ornament, and could only be bought by very rich persons." Southey in his "Letters from Spain," London, 1797, p. 118, says, "The old palace of Buen Retiro is converted into a royal porcelain manufactory; the prices are extravagantly high, but they have arrived at great excellence in the manufacture. The false taste of the people is displayed in all the vases I saw there, which though made from Roman models, are all terminated by porcelain flowers."
