Abstract (en)

[origin: WO2014169399A1] The invention relates to a method for producing a ceramic glass disc, having the following steps: providing a green glass disc, mechanical abrading and/or polishing of the green glass disc subsequent to the abrading and/or polishing, and ceramising the green glass disc to form the ceramic glass disc. It has surprisingly been found that polishing time and polishing outlay can be significantly reduced if the glass is polished before the ceramising step.
