Bricks issued from the royal workshops were sometimes stamped with the cartouches of the reigning monarch; while those made in private factories bore on the side a trade mark in red ochre, a squeeze of the moulder's fingers, or the stamp of the maker.

By far the greater number have, however, no distinctive mark.

Burnt bricks were not often used before the Roman period (Note 4), nor tiles, either flat or curved.

Glazed bricks appear to have been the fashion in the Delta.

The finest specimen that I have seen, namely, one in the Gizeh Museum, is inscribed in black ink with the cartouches of Rameses III.
