9 Portuguese blue and white tiles made in the second half of the 17th century. Decorated with ferroneries pattern. All four tiles have some chips to corners and sides. And there are some glaze mistakes. These tiles were mostly used to cover walls from important buildings, chapels and churches. Portuguese antique tiles in general are made primitively and therefore size, shape and thickness can vary a little. Backside of the tiles is cut as can be seen on the pictures; this is usually the case with 17th century Portuguese tiles. More on this tile in J.M. Dossantos Simoes, volume 1, page 57.
