How to Master the Production Quality of Ancient-Style Blue Bricks

The quality of ancient-style blue bricks hinges on every step of the production process. Ensuring quality control throughout the production is crucial for the success of blue brick manufacturing.

Maintain the soil quality; good clay is the foundation for producing fine antique bricks. As the name implies, clay is soil with粘性, so we select it, avoiding sandy and rocky soil, and soil with too little粘性. Before pressing the brick blanks, if the clay is too dry, it can cause cracks during the drying process, leading to broken bricks. If the clay contains too much water, it's prone to damaging wet blanks during stacking. Therefore, it's crucial to ensure the clay has the right level of moisture.

Then, during the air-drying process of the brick blanks, be mindful not to expose them to direct sunlight in summer. Before manufacturing the bricks in winter, check the weather forecast. If there is expected frost or snow within the next three days, abandon the brick-making process. Such weather conditions can cause the moisture in the wet bricks to freeze, damaging the structure of the仿古青砖 brick blanks.

Furthermore, after the bricks are air-dried, they are ready to be fired. First, the kiln floor must be leveled, with the bottom bricks made of fired replicas of ancient blue bricks, forming a level foundation. Second, the dried brick stacks must be arranged neatly, ensuring each brick bears an even load, allowing them to remain as stable as a mountain during the firing and cooling processes.

Additionally, the two processes of firing and cooling the water are critical, requiring technical expertise. It is essential to ensure the firing time, during which technicians observe and confirm that all ancient kiln bricks have reached the right temperature before sealing the kiln for water cooling. The water cooling must continue for several days until complete cooling, ensuring that the kiln has an adequate water supply, the kiln door is sealed, and the cooling is considered complete when no white steam rises from the kiln roof.
