A method for the three-dimensional decoration of a substrate (11) to produce an external part (10), which method includes the steps of: depositing an enamel base layer (12) on an external surface (110) of a ceramic substrate (11); firing the substrate (11) covered with the base layer (12); etching the base layer (12) in a predefined decorative pattern to generate one or more blind cavities; depositing a decorative layer (13) of ceramic material and/or metallic material on the base layer (12) and the cavities (120) so as to fill said cavities (120) in order to form decorative elements (130); surfacing the decorative layer (13) to remove said layer deposited on the base layer (12); and tribofinishing the substrate (11), the base layer (12) and the decorative layer (13) to remove the base layer (12).

The present invention extends to methods for attaching a piece of glass to a piece of stone. In some aspects, specifically designed glass inlays are secured within a void in a piece of stone. The glass inlays can include colored glass letters, numbers, designs, etc. In some aspects, glass inlays and voids are specifically designed to match one another. Glass inlays can be affixed within the voids using an adhesive. Grout can then be used to set the glass inlays in place. The result can be monument or marker that commemorates an event or person.

A timepiece dial including a base having a first region having a coating film provided at the surface of the base, a second region where laser light is radiated to the first region to remove the coating film, and a third region, in part of the first region, where the coating film is penetrated and the base is dug down, and the surface roughness of the third region is smaller than the surface roughness of the second region.

A process for forming an inlay in a cured concrete structure includes forming a pocket in a preexisting concrete structure, filling the pocket with a cementitious mixture, curing the mixture in the pocket to form a cured mixture, and polishing the cured mixture in the pocket. The cementitious mixture includes a Portland cement, an admixture comprising at least one of a strengthener, a plasticizer, or an accelerator, and an aggregate.
