What is the earliest use of the earliest finishing techniques in architecture?

The earliest building in the earliest finish technology is the earliest use of the ancient West Asian people, the first period is four thousand years BC, some of the important parts of the important buildings, while the adobe is still damp and soft, wedged into the conical ceramic nails about 12 centimeters long. The pegs were tightly packed together and the bottom surface was shaped like a mosaic, which was painted in red, white and black to form a variety of patterns. The second period is after three thousand BC, due to the local oil, more asphalt to protect the wall, more convenient than ceramic nails construction, more moisture-proof, so ceramic nails are gradually eliminated.

In order to protect the asphalt from the scorching sun, and outside of it to paste a variety of colors of stone chips and shells, to use ceramic nails to do a large area of colorful finishes to maintain the tradition. The third period is about the second millennium BC, the two rivers downstream in the production of bricks in the process of the discovery of glaze, its waterproof performance is good, beautiful color, and do not need to rely on nature like stone and shell collection, therefore, gradually became the most important region of the finishing materials, and spread to the upper regions and the Iranian plateau.

The level of lapidary decoration was so high that a whole set of practices was developed. Two kinds of compositions were formed, one with the whole wall as a painting, up and down in several segments to deal with, the subject is repeated horizontally and the upper and lower segments are different, and the other is a uniform arrangement of one or two kinds of animal statues on a large wall, simple and constantly repeated.
