DZ- has put in 2 hrs since TW told him 6hrs more might be needed. He will be polishing tonight with CeO2 http://www.ceroxid.com/html/cerium_oxide.html after settling in the tool on the mirror blank. JW explained that during polishing glass is moved from one area to another, not removed. Also, some of the CeO2 polishing compound will be embedded in the mirror.
