In the districts of SE England, where good stone is lacking, important country mansions (such as Layer Marney and Sutton Place) had ornamental detail of molded terra-cotta; on Hampton Court, Wolsey employed Italian workmen, who produced portrait medallions and other decorations of merit.

Another sample, however, showed a larger peak at 365°C and could not be dated because of serious fading.

Five samples of pottery sherds exhibited peak TL at about 275°C and 395°C gave the TL age ranged from 2.13 ± 0.14 ka to 2.25 ± 0.14 ka and a mean TL age of 2.20 ± 0.15 ka, with a good plateau in the range of 290–400°C.Hollow blocks or tiles of rough terra-cotta are used extensively as a structural material for walls and partitions, for floor arches, and for fireproofing.In modern practice terra-cotta is manufactured from carefully selected clays, which, combined with water and vitrifying ingredients, are put through a pug mill or other device to reduce the mass to homogeneity.The towns of Lombardy, Emilia, and Venetia are rich in brick buildings (e.g., the Certosa di Pavia, begun 1396) that are decorated with a profusion of molded terra-cotta detail, such as cornices, stringcourses, window frames, and other exterior ornament.Similarly, the 14th- and 15th-century brick Gothic buildings of N Germany, especially of the district around Brandenburg, had lavish displays of molded terra-cotta.The delicate tracery and other Gothic details of the Church of St.
