In 1800, the Duke of Hijar, who succeeded the Count of Aranda in the management of the manufactory, writes to D^{n} Josef Ferrer, saying: "As I do not know the authors of the pipe-clay porcelain or that of other kinds which is sent here, I beg you to order the master workmen of porcelain and common pottery to engrave, in making it, the initials of their names, as it will enable me to distinguish the good from the bad." Twelve porcelain baths with the arms of Spain in blue were made at Alcora for Queen Maria Louisa in 1800. The Duke of Hijar ordered in 1800 that a dinner-service should be made there for his use. He sent instructions that it should be of the same kind as a tea-service previously sent to his son the Duke of Aliaga. The painter chosen to decorate it was Mariano Alvaro, and the designs selected by Ferrer were taken from the Loggie of Raphael. In the same year some cases of pottery were sent to the Duke; in one of them was a fine soup tureen modelled by Josef Ferrer, Cloostermans' son, Pierre, writes at this time, asking to be appointed to the post left vacant by his father's death; his petition however was not granted. We have already seen that pottery and porcelain continued to be manufactured in the present century at Alcora in the same manner as in the 18th century, but owing to the French invasion of 1808 this industry suffered the consequences of war, and the work done there greatly diminished in excellence and quantity. Even before this the Director, D^{n} José Delgado complains in several documents of the bad state of the manufactory, the Directors who replaced him, D^{n} Juan Bautista Cabot and D^{n} Pedro Bezarco, write continually repeating the same thing. After the French were turned out of Spain, the industry was revived and strengthened by fresh artists from the porcelain manufactory of Madrid. D^{n} Luis Poggetti was appointed drawing master there in 1815, and D^{n} Domingo Palmera master of ornamental art, both these artists had worked at Buen Retiro, Poggetti as Director of pietre dure, and Palmera as second-class sculptor. After this time the manufactory of pottery at Alcora ceased to produce artistic works, and limited itself to send out common wares for domestic purposes; this system continued until 1858, when the Duke of Hijar sold the manufactory to D^{n} Ramon Girona, who brought over English workmen from Staffordshire in order to improve the wares. Many imitations of the older styles have also been made at Alcora of late years.
