Shade and caliber belong to the run
Two figures travel with every carton of porcelain. Shade is the tone the run came out of the kiln at, and caliber is its actual size, which sits inside a tolerance instead of landing exactly on the nominal figure.
Neither is a defect. A pressed clay body shrinks as it fires, and the shrinkage is never identical from one firing to the next, so the maker sorts the output and prints both codes on the carton. On a small job nobody meets the consequence; on a large one it decides whether the floor reads as a single surface.
Why a large job orders in one go
Ordering the whole quantity at once is the only reliable way to keep a job inside one shade and one caliber. A second order weeks later is a second run, and the codes on it may not match what is already down.
The same logic applies to the waste allowance. A large floor generates cuts at every wall, at every doorway and around every fixed object, and the allowance for those belongs in the first order, because that is the order whose cartons already carry the same codes.
12x24 across a large porcelain floor
The range centers on 12x24, then 8x48, with 24x48, 24x24, 8x8 and 4x12 in smaller numbers.
12x24 earns that position on a big floor for an unglamorous reason: it is large enough to cut the number of joints down sharply, and small enough that one person can handle a piece and that a slightly uneven substrate does not fight it. The larger the tile, the flatter the floor underneath has to be.
Marble look leads, wood look follows
Marble look is the largest effect here, then wood look, with fabric, concrete, stone and colore looks in smaller numbers. Carrara, Calacatta and Bianco account for most of the marble side.
On a large area a print reveals itself through repetition. A printed range is made from a set number of faces, and the more square feet of it go down, the more often a given face comes back, so the number of faces in a series matters more on a whole-house job than on a bathroom.
Matte porcelain over a large floor
Matte is the finish this range is built on, with polished, natural and semi polished groups after it.
A large floor is also a large reflector. A polished face throws back every window and every fitting across the whole span, and it shows the trace of anything that crosses it; a matte face returns the light diffusely, which is why it carries most of the volume lines.
The 8x48 porcelain plank
8x48 is the second size here and it is a plank: four feet long and eight inches wide, laid in offset courses the way a board floor is.
A four foot piece is also the format that finds a dip in a floor. A square sits over a small hollow and a long plank bridges it, so one end lifts and the corner stands proud of its neighbor. The longer the format, the flatter the surface underneath it has to be.
Thickness and where two floors meet
Most of this range is 25/64 inch, which is 10 millimeters, with smaller groups at 5/16 and 3/8 inch.
That figure matters at a threshold. Where this tile meets an existing floor of a different thickness, the difference has to be taken up in the bed underneath or covered by a transition piece, and it is easier to find out before the tile is ordered than after the first room is down.
Where this sits in the porcelain range
For the material across the whole catalog, porcelain tile is the full range, and white porcelain tile is the largest color cut of it.
Porcelain moldings is where the trim sits, and the plank effects run on through wood look tile.
