What is the size of one to nine glazed tiles from ancient times to modern times?

Glazed tiles are traditional architectural objects in China, usually coated with colored lead glazes such as gold, green and blue. As early as the Southern and Northern Dynasties in China, glazed tiles were used to decorate buildings. After the development of past dynasties, glazed tiles have formed a series of products with rich varieties, exquisite styles and strong assembly. Commonly used common tiles are: pipe tile, slab tile, sentence tile, drip tile, Luoguo tile, bending tile, beast, horn, direct kiss, angle-closing kiss, hanging beast, money beast, treasure top and so on.

Glazed tiles and western-style tiles should have good internal physical properties (flexural and compressive strength, water absorption, rapid cooling and rapid heating resistance and frost resistance), and the main inspection items are appearance quality.

The appearance of the product requires smoothness and neatness, and the glaze color is bright and pure. When the tiles are assembled together, the glaze color should be basically the same. The modeling pattern is neat and clear, and the allowable dimensional tolerance of the product is 2mm. Those who meet the above requirements are qualified. If there are drawings and samples, they should be inspected in strict accordance with the standards. There are also some special inspection methods for glazed tiles: for example, four tiles should be surrounded by cylinders, which is 360 degrees. The combination of two tiles should also form a cylinder. The included angle between the hook, the urinal and the tile should be135 5.

A. 1 transparent ruler = 18cm

B. 1 transparent ruler =26cm

C. 1 clear height feet = 32 cm
