Thun Karlovarský porcelán
Thun 1794 (official name Thun 1794 a.s.) was a German and Czech porcelain manufacturer using the porcelain mark "TK". Originally founded in 1793/1794 as Thun'sche Porcellanfabrik and, after many restructurings, finally closed in 2024 after 230 years, it was the oldest and largest Czech porcelain manufacturer. It operated in three locations: Klášterec nad Ohří (formerly Klösterle an der Eger), Sadov-Lesov (formerly Sodau-Lessau) and Nová Role (formerly Neurohlau).
