Short answer
Drop water on the back of a tile and wait 60 seconds: true porcelain absorbs 0.5% or less, so the water beads instead of soaking in. That is what decides frost resistance and ten years of traffic on a commercial floor — and we run it on every production batch before packing.

Drop water on the back of a tile and wait sixty seconds. On a dense porcelain body, the water sits there — beads on the surface, barely moving. On a porous body, it soaks straight in. That difference is water absorption, and for commercial projects it’s the number that matters: true porcelain absorbs half a percent or less, and that’s what decides frost resistance, stain resistance, and how the floor survives ten years of traffic. Spec sheets can claim anything — this test is run on the actual production batch before it ships.
