Abstract
A method for the manufacture of colored structures of a glass, particularly for applying an inscription to the glass, by locally heating volume elements of the glass by means of a laser beam, which glass contains ions of metals which, in the form of submicroscopic particles, color the glass wherein the local heating of the non-doped glass is accomplished through a solution or gel of a metallic salt which transmits the laser beam well and is directly contacted with a surface of the glass.
Claims10
A method for the manufacture of colored structures in a glass surface, particularly for applying an inscription to the glass, comprising the following process steps:
- Providing the glass surface of a non-doped glass with a solution or gel of a metallic salt suited for coloring glass that transmits the laser beam well,
- Directing a laser beam onto the solution or gel on the surface in an area to be colored,
- Heating the area to be colored by the incident laser light, characterized in that
- the temperature of heating in the area to be colored is lower than a temperature required for causing the surface to melt.
A method for the manufacture of colored structures in a glass surface, particularly for applying an inscription to the glass, comprising the following process steps:
- Contacting a substrate containing a solution of a metallic salt suited for coloring glass directly with a surface of a non-doped glass with the substrate transmitting the laser beam well,
- Heating an area to be colored by means of incident laser light, characterized in that
- a laser beam is directed onto the surface through the substrate and the substrate is transparent to the laser beam, and
- the temperature of heating in the area to be colored is lower than a temperature required for causing the surface to melt.
