Abstract: An apparatus and a method for producing pasty paraffin from liquid paraffin comprises the use of an agitator for mixing the paraffin during its solidification within a receptacle. The viscosity of the paraffin is controlled by the monitoring of the power of a motor driving the agitator. Also, an apparatus is provided for producing candles in bottles from the pasty paraffin produced hereinabove. The apparatus comprises a filling head which receives the pasty paraffin and a continuous wick. A device is included for positioning a ferrule on the wick with the filling head being adapted for lowering into the bottle for positioning the ferrule at the bottom thereof and being also adapted to inject pasty paraffin in the bottle for setting the ferrule. The filling head is then retracted slowly from the bottle while injecting further paraffin therein for filling to a selected level the bottle.
