Directions in full.--First polish the iron you are about to plate, then wet it with soldering fluid, (receipt No. 21,) then give it a coat of solder, (receipt No. 22;) this is done by laying a piece of solder on the iron, and spreading it over with a heated soldering iron; or it is sometimes done by having the solder melted, and then dipping the iron to be silvered into it. After the iron is coated by either of these methods, with solder, some workmen propose to then place it in the fire for a few moments, that the coating of solder may be thereby made smoother. The next thing to be done is to dampen with soldering fluid, then lay on your silver foil, and rub it over with a soldering iron heated to such a degree as to melt the solder, and thereby fasten the plate at once to the iron; or rather to the solder on the iron; or else as some workmen prefer, have your soldering iron only hot enough to slightly stick the foil to the solder, and then place the article in the fire until the solder melts, and thereby the foil becomes firmly united with the iron. Whichever of these methods you adopt, as soon as the silver is united to the iron, you must then at once proceed to polish it, which is done by taking a piece of coarse cloth, dipping it in whiting, previously dampened with alcohol, and rubbing it over the surface until it is well polished. If at any time, as sometimes will happen, the plate of silver becomes stained so that you cannot polish it, wet it with the fluid, put another plate of silver foil over it, and proceed to fasten it to the iron as you did with the first plate,then polish it with the whiting, &c. Some merely spit on the whiting instead of dampening it with the alcohol, but it is not so speedy a method. A friend of mine prefers heating the iron, then applying the soldering fluid, then the coat of solder, and then laying on the silver foil, and pressing on by means of a cloth, which he does by taking a piece of cloth about four inches wide and eight or ten inches long, catching one end in each hand and pressing and rubbing it from side to side, and round the article until the silver foil is firmly united, and then polishing as mentioned above. Some prefer plating the iron first with tin foil, then covering the tin with silver foil, and it is a good plan. A very good plan, if it is plane work (not carved) you are doing, is to take a piece of board one or two inches wide, and six or eight inches long, and lay it over the cloth you are polishing with, which gives you a greater purchase. I never knew this receipt to be sold for less than from $24 to $60. TO ALL WHO HAVE PURCHASED THIS WORK
