Polish the iron toy wish to silver, then damp it over with soldering fluid (receipt No. 21) When this is done give it a coat of No. 22 solder. This is done by laying a piece of cold solder on the iron, and spreading it over with a heated soldering iron, when by this means you get the iron nicely plated with solder, then lay on your silver-plate evenly, and gently rub it over with the heated soldering iron, and it will become firmly united with the solder as the solder is with the iron, so that you have the iron beautifully plated with silver with very little cost or trouble. 24. HOT METHOD OF SILVERING IRON WITH SILVER-PLATE First polish the iron you wish to silver, wet it well over with No. 21 soldering fluid; then having procured that kind of silver-plate which is tin on one side and silver on the other, place it evenly on, with the tined side next to the iron, then place it on the fire until the silver-plate melts down, then at once take it from the fire, and it will be firmly attached to the iron, and will be excellent plate; yet No. 23, the cold method, is to be preferred in most cases. 25. SILVERING LOOKING-GLASSES WITH QUICKSILVER Take a piece of marble or some other substance very smooth, true, and level, lay on this the glass you wish to silver, then make a ridge of putty on the marble against the edge of the glass all round it, so that you can pour quicksilver on the glass until it is all covered over, and will be prevented from running off by the ridge of putty; an inch or two, or three outside this ridge make another of putty; then cover the quicksilver on the glass all over with tin-foil, and press it firmly but cautiously against the glass until you have squeezed out all the quicksilver you can. While you press this, you may remove part of the first ridge of putty to give the quicksilver a chance of escape. When it is well pressed against the glass there will be an amalgam formed of the tin-foil and the quicksilver that is left, which will firmly adhere to the glass. By this means you have a very beautiful and cheap looking-glass; the quicksilver that escapes, being saved by the second ridge of putty, may be used again. 26. SILVERING LOOKING-GLASSES WITH PURE SILVER Prepare a mixture of 3 grains of ammonia, 60 grains of nitrate of silver, 90 minims of spirits of wine, 90 minims of water; when the nitrate of silver is dissolved, filter the liquid and add a small quantity of sugar (15 grains) dissolved in 1-1/2 oz. of water, and 1 1/2 oz. of spirits of wine. Put the glass into this mixture, having one side covered with varnish, gum, or some substance to prevent the silver being attached to it. Let it remain for a few days and you have a most elegant looking-glass, yet it is far more costly than the quicksilver. 27. PATENT BURNING FLUID
