The manufactory produced yearly about 300,000 specimens of different kinds. The ordinances are interesting which in 1732-1733 prescribe, "that in our manufactory only pottery of the most excellent kind should be made, similar to the Chinese, to be equally fine as to the earths employed, that the models and wheels should be perfect, the drawing of a first-rate kind, and the varnish and colours excellent, and the pottery light and of good quality, for it is our express wish that the best pottery should only be distinguished from that of an inferior kind by the greater or less amount of painting which covers it."

Miguel Soliva, Christobal Cros, Francisco Grangel, Miguel Vilar, Christobal Rocafort, Vicente Serrania, and Joseph Pastor were the best painters at Alcora in 1743; they decorated a fine dinner service made for the Tribunal of Commerce, and the large slabs for the Convent of Las Descalzas Reales at Madrid, representing the Virgin as the Divine Shepherdess.

Pottery painted with metallic lustre was made in 1749. We find among the receipts used in that year one brought from Manises for this object.

We find it also stated in the communications which passed between the Tribunal of Commerce and the count in 1746, that "the perfection of the earthenware of Alcora consisted in the excellent models which had been made by competent foreign artists, the quality of the earth and receipts brought at great expense from abroad." Joseph Ochando is mentioned in that year as an excellent painter, and Juan Lopez as the best carver and modeller. This document tells us "that from the earliest period of the manufacture pyramids with figures of children, holding garlands of flowers and baskets of fruits on their heads, were made with great perfection, likewise brackets, centre and three-cornered tables, large objects, some as large as five feet high, to be placed upon them, chandeliers, cornucopias, statues of different kinds, and animals of different sorts and sizes. The entire ornamentation of a room has also been made here; the work is so perfect that nothing in Spain, France, Italy or Holland could equal it in merit."

The objects which were made to a great extent at this time consisted in:

In 1750 Count Aranda passed the pottery works on to a private company, in whose hands they remained until 1766. We know the pottery continued to be excellent. Unfortunately almost all the details of this period are missing from the Archives. One of the few documents remaining is a contract drawn up in October, 1741, with François Haly (the name of this artist is given by Baron Davillier), a Frenchman, in which he agreed to work at the manufactory during a period of ten years with a yearly salary of over 1000 francs, under the following conditions:

"That the travelling expenses of his wife and children should be given him, and that his salary should be paid as soon as he made before the Director and two competent judges the different kinds of porcelain which he had undertaken to make." He agreed to give up his receipts, and it was promised him that he should have two modellers and one painter working by his side, and that if in one year Haly's porcelain was satisfactory the Count undertook to make him a present of 1000 livres (tornoises).

Towards the middle of the century, porcelain was made for the first time at Alcora. A contract was drawn up on 24th March, 1764, with a German, called John Christian Knipfer, who had already worked there in the pottery section. By the original agreement, which exists at the Archives, we find he was to prepare works of "porcelain and painting similar to those made at Dresden, during a period of six years, under the following conditions:"

"That the said Knipfer obliges himself to make and teach the apprentices the composition and perfection of porcelain paste, its varnishes, and colours, and whatever he may know at the present time, or discover during this period of six years; he is not to prevent the Director of the Works from being present at all the essays made."
