The four surviving University Wafers 76.2mm/0.5mm wafers have been CO2 polished. They are identified by numbers from 1 to 4 on the container. Number 4 was used for tests, so it might not be as good as the other three. During number3 polishing, the CO2 laser tripped, so I restarted the process from the beginning.
