Don Carlos de Borbon was a black slave who had been captured with other blacks during the reign of Ferdinand VI. The Queen-mother sent them to Naples, and Charles III. gave them an artistic education. Don Carlos Antonio became the King's architect. On the 22nd of May, 1760, the building was finished, the money then spent amounted to upwards of 145,000 reals, and Larruga tells us, in his Memorias, "The King spent in establishing this manufactory £115,000, with a yearly cost to keep it up of £20,000." William Clarke, in his "Letters concerning the Spanish Nation during the years 1760-1761," London, 1763, says, p. 262: "At Madrid is lately set up a manufacture of porcelain in the gardens of the King's palace at the Retiro, wrought by artificers brought from Saxony." Documents exist proving that in 1760-1761, they were already working there. Townsend, in his "Journey through Spain in 1786 and 1787," London, 1792, says, Vol. II., p. 278:-- "I tried to obtain admission to the china manufacture, which is likewise administered on the King's account, but His Majesty's injunctions are so severe that I could neither get introduced to see it, nor meet with any one who had ever been able to procure that favour for himself. I was the less mortified upon this occasion because, from the specimens which I have seen, both in the palace at Madrid, and in the provinces, it resembles the manufacture of Sèvres which I had formerly visited in a tour through France." In the "Nouveau voyage en Espagne, ou Tableau de l'état actuel de cette monarchie," Paris, 1789, Vol. I. p. 233, the author tells us, how "Le monarque actuel à établi dans leur interieur une fabrique de porcelaine, dont l'entrée est jusquà present interdite à tout le monde. On veut sans doute que ses essais se perfectionment dans le silence, avant de les exposer aux yeux des curieux. Ses productions ne peuvent encore se voir que dans les Palais des Souverains, ou dans quelques Cours d'Italie, auxquelles il les envoie en presens." We find in a "Nouveau voyage en Espagne," Paris, 1805, p. 34, in describing this porcelain manufactory that the author says; "Cet établissement tres couteux ne travaille que pour le Roi et a son compte; il en sort des vases d'une beaute et d'un fini qui ne le cedent point à ceux de Sèvres." Citoyen Alquier, in 1800, the envoy of the French Republic, was allowed to visit the manufactory.
