Coated metal part comprises a layer impermeable to H 2 and O 2 arranged on the side facing away from the glass melt. An independent claim is also included for a process for coating metal parts. Preferred Features: The layer impermeable to H 2 and O 2 is temperature-resistant and is elastic, liquid or solid. The layer impermeable to H 2 and O 2 is made from a glass containing (in wt.) 40-99 SiO 2, 1-30 Al 2O 3, 0-30 B 2O 3, 0-15 BaO, 0-20 CaO, 0-8 MgO, 0-5 ZrO 2, 0-25 sum of alkali oxides, 0-10 P 2O 5, 0-3 Cr 2O 3, 0-10 TiO 2, 0-10 Fe 2O 3, 0-5 ZnO, 0-10 MnO, 0-10 SrO, 0-70 PbO and 0-1 F. |
