The invention relates to a process for coating fibrous glass with a glass metal mainly consisting of nickel-phosphorus, under conditions free of current. According to the process a fibrous glass substrate is treated with an aliphatic alcohol having 1 to 4 carbon atoms and subsequently with an aqueous solution of SnCl2, in the presence of hydrochloric acid, and is then activated with a solution of palladium chloride in aqueous hydrochloric acid. Thereafter the pretreated and activated substrate is kept in a bath comprising nickel ammonium sulfate or nickel sulfate and nickel ammonium sulfate as a nickel-containing component, in combination with sodium hypophosphite, an alkali metal salt of at least one organic acid having a low molecular weight, a mineral acid, preferably sulfuric acid or hydrochloric acid in an amount sufficient to adjust the pH to 3 to 4, and optionally organic or inorganic metal-deposition regulating agent(s) at a temperature between 50 DEG to 90 DEG C.
