Abstract
A method is provided for producing a raised feature on a glass ceramic element, in which a glass or glass ceramic element is irradiated with electromagnetic radiation in a local region of the surface, the radiation passes through the element and is at least partially absorbed thereby so that the element heats up in the region of the irradiated electromagnetic radiation and is heated beyond a glass transition temperature. The irradiation is terminated after heating so that the heated region cools down to the temperature of material surrounding the local region. The heating causes a change in volume of the element, which brings about a local elevation in the surface that remains after the local region cools so that a surface deformation in the form of an elevation remains after cooling.
