3. Drying
The formed tiles are dried to remove excess moisture. This step is crucial to prevent cracking or warping during the firing process. The drying process can be done naturally or using industrial dryers, depending on the scale of production.
4. Glazing (Optional)
For glazed tiles, a layer of liquid glass is applied to the surface of the dried tiles. The glaze can be applied using different techniques such as spraying, pouring, or dipping. This step is optional for unglazed tiles.
5. Firing
The dried or glazed tiles are fired in a kiln at high temperatures, typically ranging from 1000 to 1250 degrees Celsius. The firing process hardens the tiles and fuses the glaze to the surface, creating a durable and impermeable finish. The firing time and temperature are carefully controlled to achieve the desired properties of the tiles.
6. Sorting and Packaging
After firing, the tiles are sorted based on quality, size, and color. Any defective tiles are removed, and the rest are packed and prepared for distribution. Quality control is essential to ensure that the tiles meet industry standards and customer expectations.
