Abstract
A process for manufacturing glazed ceramic tiles from a substrate of green clay having at least one groove extending within the surface of the tile, wherein the groove is imparted to the tile while the substrate is still green clay before the substrate is bisque or glaze fired. A tile fabricated using this process is also part of the invention.

A method of manufacturing a glazed ceramic tile with at least one groove to receive grout to replicate the appearance of multiple tiles comprising the steps of:
- a) initially, providing a substrate of green clay wherein the substrate has a first surface that is flat and planar, an opposing second surface, and a depth between the first surface and the second surface;
- b) after the step of a), but before the step of c), drying the green clay to remove moisture from the substrate;
- c) after the step of b), but before the step of d), imparting at least one groove within the second surface of the substrate in the green state, wherein the groove has a depth that is between 50-67% of the depth of the substrate;
- d) after the step of c), but before the step of e), applying a layer of glaze upon the second surface;
- and
- e) after the step of d), glaze firing the substrate wherein the substrate is vitrified into ceramic and the glaze is melted onto the second surface of the substrate.

- c) after the step of b), but before the step of d), imparting at least one groove within the second surface of the substrate in the green state by machining the substrate to produce at least one groove, wherein the groove has a depth that is between 50-67% of the depth of the substrate;
- d) after the step of c), but before the step of e), applying a layer of glaze over the second surface;
- and
- e) after the step of d), glaze firing the substrate with the glaze thereupon wherein the substrate is vitrified into ceramic and the glaze is melted onto the second surface of the substrate.
