The basic body of the salt is formed of slabs of white clay, stamped and incised with designs in clays that show through the glaze as orange brownish and flecked red; there is applied decoration in pale brown and orange-brownish clays. The salt is covered entirely in a somewhat crackled transparent glaze, and the design is heightened in green and purple red. There are repairs to the feet and some shrinkage, chipping, and cracking where the underside of the base meets the edge: there is, however, nothing to support the statement in Bonnaffé 1891 that "la base de cette saliére a été refait d'après une autre pièce de la série des faïences de Saint-Porchaire," repeated in the Widener collection records ("the base is remade from another example"); no evidence has been found that the salt is not essentially in its original condition. There are minor repairs to the protruding ridge.
 It seems tha Bonnaffé confused this salt with one now in Brussels, which is stated by Delange and Delange 1861, no. 16, to have lost its original foot. Anne-Marie Mariën Dugardin kindly made a special examination of the Brussels salt for me, which confirmed that its foot is a replacement.
