In the year 803, at the Council of Reims, the use of chalices made with materials of vegetable and animal origin was forbidden, since the blood and body of Christ could only be in contact with precious metals.
In GRANDA all the vessels are double. The interior is always made of gilded silver, considered the best material to be in contact with the body and blood of Christ. The outer cup, which holds and supports it, is made of silver with different finishes. Wood is never used, as it is porous and can leak wine, nor ceramic, which, when dropped, can break and spill the wine.
This new collection of chalices is based on the Romanesque (and neo-Romanesque) style, which was the predominant artistic style in Europe during the 11th, 12th and part of the 13th centuries. It was the first great clearly Christian and European style that brought together the different options that had been used in the early Middle Ages and managed to formulate a specific language that was applied to all artistic manifestations, both architecture and art.
It arose as a consequence of the material prosperity and spiritual renewal that inspired the construction of a large number of churches and religious buildings.
