In the last step of fabrication, optical and fine optical glasses are polished to fulfills the optical requirements for their surfaces. The major influences on the process are caused by the mechanics of the polishing machine, by the chemistry (composition of the glass, as well as the polishing suspension of water and polishing grains, CeO2) [1], [2] and by the material and structure of the polishing pad. From previous own results [3], [4] it is known that the stability of the colloidal systems has a major impact on the polishing results and that it is influenced by matter from the glass removal. Thus the g;asses have been classified in glass families, depending on their chemical composition and their mutual comparability in the process. As it is not always possible to measure this compatibility, the impact of the various dissolved glass...
