These markings on nominal 10mm x 10mm tiles were done using the teachings of US 6518542. Here a black frit patch is ablatively removed (negative image) prior to firing

Mullite 10 mm x 10mm      Size             Hot 2x3           
       Mullite 10 x 10 mm                                   Size Comparison                    2"x3" Alumina at 2400 deg F.



These markings are on a ceramic tile which has been fired to 2150 deg. F . The codes and tiles can be any size and would be reusable for tracking parts through through chemical or high temperature processes.

Blank CeramiCodes™ can also be printed on site with piece specific information.





This alumina tag is inserted into a pocket which presents the affixed tag below the surface plane. It therefore cannot be scraped off as the block is scraped during processing.

TRANSFER CODES
One method of applying bar codes directly onto ceramics is to preheat the ceramic part  ( to approximately  175 Deg C) and then pressure transfer a precut bar code code pattern from a sequential "tape". These codes can survive more than 850 deg C.  See the heating and transfer in a movie which you can download  Here
