These markings on
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 x 10
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
which presents the affixed tag below the surface plane. It therefore
cannot be scraped off as the block is scraped during processing.
alumina tag is designed for long term , high temperature applications.

One method of applying bar codes directly onto ceramics is to preheat
the ceramic part ( to approximately 175 Deg C) and then
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
