Abstract

Steel container 3, provided with an internal enamel layer, as a water reservoir which has a wall section 4, a bottom 7 and a lid 8, which likewise consist of sheet steel. The contact points of lid and bottom respectively with the central section are in the form of welded seams 18 whose inner sides in the region between two boundary lines 22 and 23 are wetted, prior to application of the enamel slip, with an aqueous solution or slurry of an alkali metal or alkaline earth metal sulphate or chloride, preferably sodium sulphate or chloride or magnesium sulphate or chloride, zinc sulphide, nickel oxide or cobalt oxide. <IMAGE>
