Abstract
Abstract A process for selectively decorating a transparent, glassceramic body or a thermally crystallizable glass body by the steps of coating selected surface areas with a compound or composition which is capable of selectively absorbing electromagnetic radiation, exposing the coated area to a source of electromagnetic radiation for a period of time so as to cause the glass-ceramic or glass body immediately under the coated areas to be heated to effect formation of opaque glass-ceramic surface areas on said body.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
30 words
The process as defined in claim 1 wherein the infrared radiation has a power intensity of at least about 1 kilowatt at a voltage of at least about 90 volts.
Claim 2
Dependent Claim
19 words
The process as defined in claim 1 wherein the body is formed of an aluminosilicate glass or glass ceramic.
Claim 3
Dependent Claim
241 words
A process for producing in situ crystallization within the surface layer region of an articlE formed of a thermally crystallizable glass or an article formed of a partially crystallized glass capable of conversion to a more highly surface crystallized condition, comprising the steps of: coating at least a selected surface portion of said article with a removable electromagnetic radiation absorbing coating composition possessing the characteristics of absorbing and converting high intensity electromagnetic radiation into heat; said composition being selected from the group consisting of graphite, metal oxide and powdered metal, exposing the resulting surface coating to a source of energy consisting essentially of infrared radiation having a wavelength of from 1.1 to about 2.5 microns for at least about 0.25 minutes which is of sufficiently high intensity to be absorbed and converted by said surface coating into sufficient heat to rapidly elevate the temperature of said surface coating to a temperature within the thermal crystallization temperature range of the article, and thereby heating the surface coated portion of said article by permitting such converted heat to flow from said surface coating to the underlying coated surface layer portion of said article, continuing said radiation for sufficient duration to initiate nucleation and thermally crystallize a substantial portion of said underlying surface layer in said selected portions of the article, said radiation heating being insufficient to fuse said coating composition to said article and said coating being removable from said article by washing.
Claim 4
Dependent Claim
