To produce high-quality blue tiles, it is essential to first control the soil quality. As the name suggests, clay is a type of soil with粘性. If soil containing sand and stones is not chosen, soil with lower viscosity will not be selected.

If the clay is too dry before pressing the bricks, it can cause cracking during the drying process in the shade, leading to brick breakage. If there's too much moisture in the clay, stacking it can damage the wet bricks. Therefore, it is crucial to ensure the clay has the right humidity. Air-dry the brick molds. In summer, be cautious not to expose them to direct sunlight. In winter, check the weather before making the molds. If there's frost or snow in the next three days, abandon the preparation as this weather can freeze the water in the blue tiles and damage their structure.

The green tiles are placed into the kiln. Firstly, bricks should be laid at the bottom of the kiln, and the fired green tiles should be used to form the base. Secondly, dried steel billets should be stacked to ensure balanced force on each brick, maintaining stability during the firing and cooling process for drinking water. During this time, there must be sufficient water in the kiln, and the kiln door must be sealed. The cooling process is considered complete when no more white steam is released from the top of the kiln.

Only through strict control of every detail during the production of green tiles can they become both beautiful and durable. Furthermore, from the evolution of colored glazed tiles, it is essentially a type of glazed tile. The difference from common glazed tiles mainly lies in the glaze color. Vintage tiles belong to the category of common tiles, similar to ceramic tiles. The term "vintage style" refers to the effect of the tiles and should be called "vintage effect tiles." Vintage tiles are not difficult to clean.

Differences lie in the higher technical content of antique brick manufacturing during the firing process. After being compressed by thousands of tons of hydraulic presses, these bricks are sintered at 1,000 degrees Celsius, boasting high strength and excellent wear resistance. Through careful research and development, antique bricks feature waterproof, anti-slip, and corrosion-resistant properties.
