Huizhou architecture is characterized by black tiles, whitewashed walls, and horse-head walls; brick carvings, wood carvings, and stone carvings are decorative features; high houses, deep wells, and halls are home features. Bricks, tiles, stones, and wood are the main materials used for construction. Brick and tile firing techniques have played a very important role in the development of Huizhou architecture. Huizhou folk brick and tile firing techniques are extremely complicated. The process of making blanks alone requires seven processes, including selection, ice, grinding, slurry, screening, leaching, and training. Brick and tile firing is a job with very high technical requirements. The kiln master masters the eight elements of distinguishing temperature, color, fire, sound, smoke, ash, saltpeter, smoke, and smell according to the four properties of blanks, kilns, climate, and fuels, and adjusts them in time to fire fine bricks and tiles. At present, the types of brick and tile products of Huizhou ancient buildings are rich. Brick products mainly include plain bricks, square bricks, strip bricks, gold bricks, swastika bricks, Ruyi bricks, drum bricks, water-covered bricks, rolling ridge bricks, carving bricks, calligraphy bricks, fixed-shaped engraved bricks, special-shaped bricks, etc.; tile products mainly include tiger-faced tiles, flower-edge tiles, tubular tiles, dripping tiles, cucumber ring tiles, groove tiles, green tiles, green tiles, square buckets, bird tails, animals, ridge beasts, ridge kisses, chicken beasts, aoyu, landscapes, figures, fish, insects, birds, grass and various animal and plant shapes.
