Abstract
The present disclosure relates to a process for fabricating glass tooling with a featured surface. The method entails the steps of coating a polished surface of a glass blank with a continuous metal coating. A photoresist is applied, exposed, and developed in a desired pattern. Uncovered metal is etched away and the remaining metal provides a mask. The uncovered glass is plasma etched to feature the surface of the glass blank.
