They're going to wear those tiles out just in handling them alone.
Rough cut as the clay is forced out of the extruder handed off to a guy placing them on a cart then it looks like they were stacked on the ground by the guy doing the trimming with his knife and the shape form. then he stacks them once again on the ground, which means they will have to be handled again to be loaded on a cart to take them to the kiln, where someone will have to remove them from the cart and place them in the kiln. After firing they will need to be handled who knows how many times before reaching the roof of a building
