In a process for producing a glass blank or workpiece from which a glass fiber light conductor of a low attenuation is drawn, said workpiece being formed by providing a body on which amorphous glass powder is precipitated from a reaction gas after a chemical reaction and then transformed into a clear glass characterized by the reaction gas being passed over or through a powder composed of amorphous glass of the same type which is being precipitated from the reaction gas onto the body to filter impurities therefrom. Preferably, the amorphous powders of the filter are contained in a precipitator and are produced by also reacting the gas and collecting the powder in the precipitator.
