Comment on why are ceramic tiles always stacked facing the same direction, smooth side against rough side?

But for one batch of tiles the stack was a bit rocky - less stable. Whereas the original stack of all facing the same direction does not rock. Apparently they are less flat or less symetric than they appear.

One side is slippy, one side is grippy.

Stack grippy to slippy, and a stack is structurally sound.

Stack only grippy to grippy and slippy to slippy, and it’s gonna tumble.
