Marès built up his own ceramics collection (a common theme among collectors) and set aside five rooms for it. A wide variety of objects are on view, dominated by products from the main Spanish workshops-Talavera de la Reina, Puente del Arzobispo, Manises, Alcora, Muel, Teruel and Catalonia. The cracked glass glaze is a characteristic they all have in common.

The halls which are dedicated to ceramics (halls 10 and 11) feature a varied collection of holy water fonts. These stoups are small water holders, which are meant for purposes of private devotion, and which were hung on the wall or on a piece of furniture. They are generally composed of a small cup and a wall plate and are often decorated with religious iconography. The cup held water that had been blessed by a priest, which the faithful used to bless themselves in a purification ritual.

This collection contains a wide range of shapes and techniques which includes popular works and more professional pieces. Most of these are from 18th and 19th century Spanish studios like Talavera, Manises, Alcora, Teruel, La Granja Royal Glass Factory, and others.

In the middle of the first gallery there are 31 glass fonts, an age-old tradition in Catalonia and Mallorca. Their whimsical shapes stand out, having been crafted by master glass blowers.

On the upper section of the walls in the second room, notice the collection of ceramic tiles. These are mainly from 16th century Catalonia and Valencia. Decorated with heraldic motifs, they were used to adorn the floors and walls of monasteries, convents and civil buildings. One of the sets included in the collection is decorated with the symbols of various abbots-it comes from the Cistercian monastery of Poblet.
