There is no need for separate glassware, from the standpoint of halacha. If there is any metal (i.e., gold plating or stainless steel design) on the glass, it probably would become an issue, but as I have never had that type of glassware, I am not sure, so ask your LOR. I rarely use real glassware, but have cups. I have completely separate fleighig and milchig ceramic mugs for coffee and tea.
