Abstract:
1. A method of creating an engraved image on a surface of a stone substrate, the molecular content of which includes silicon and oxygen, comprising the steps of: digitizing an image; defining an image-receiving area on the surface of said substrate; coating the image-receiving area on said surface with a breathable primer having a chemical content including silicon and oxygen compatible with the mineral content of the substrate; overcoating the primed area with a first pigmented, durable polysiloxane paint of a first color and having a chemical content related to the mineral content of the substrate and the primer; using the digitized image, laser etching an image into the overcoated area by creating a digital pattern of blind holes of uniform depth in the overcoating paint and into but not beyond the primer; overcoating the etched area with a polysiloxane paint of a second color contrasting to the first color to fill said blind holes; and sealing the image area.
