To re-solder a spout on a copper kettle, first thoroughly clean the copper where the spout is to be inserted with apiece of emery cloth, and also clean the spout around its large end. Then tin the copper inside the kettle where the spout is to be soldered, and also the spout, using killed spirits as a flux. Pass the small end of the spout through the hole from the inside of the kettle, and press it up so that the small flange on the large end of the spout butts against the side of the kettle; then solder round the spout on the inside of the kettle, and leave a thin body of solder floated smoothly round where the join occurs, the same flux being used as for the tinning. Solder composed of l 1/2 lb. of tin and 1 lb. of lead would be suitable for this purpose.
