ABSTRACT:
In apparatus for carrying out a method of manufacturing optical fibre preforms by causing a chemical reaction to take place in a gaseous reaction mixture so as to form a coating on a glass substrate wherein the reaction is promoted by the production of a plasma, a non-volatile component of the reaction mixture is held within a dispenser tube so that when it is evaporated by applying heat, it travels through perforations in the dispenser tube and reacts with the other components of the gaseous mixture.
