Cruets are holders for the wine and water used during Mass. They have a domestic aspect, being based on household items such as water or wine jugs. The dimensions for such articles were established after the Council of Constance (AD 1414-1418); earlier, such containers were much larger, and used for bread and wine alone.

Each of these cruets consists of a translucent glass container partly covered in sinuous silver ornamentation with silver-decorated glass stoppers and handles. Some aspects, such as the curving plant and shell motifs, acanthus leaves, and lavish floral decoration, are typical of 18^th century European taste. Despite this (mainly Italianate) influence, the overall effect of these cruets recalls the grace and elegance of Mughal- or Persian-style perfume bottles and wine ewers. The retaining bands around the cruets carry the characteristic Indo-Portuguese pearl design.

The silver base is also decorated with floral and vegetal flourishes; in its middle can be seen a winged angel. The base has handles and stands on four feet, all ornamented with plant motifs.
