Although the clay slab is soft, it does not easily deform when there is an arched support underneath, especially since these tiles are not large, and the gravitational impact is minimal.
After using the same mold, the shape of different tiles becomes very similar, and even if they slightly deform during drying, it won't affect the tiling.
Additionally, rough wooden stakes can also be used to dry the clay tiles, but they are harder to obtain, and cleaning them requires time.
Therefore, earthen mounds still need to be piled up, but their shape doesn't need to be so standard, and the height requirement is very low. You just need to lay a layer of red clay mixed with loose mud and slightly shape it.
This way, this process becomes much simpler, though it still requires a lot of effort.
