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
To 1 gallon of 95 per cent. alcohol, add 1 quart of camphene oil; mix and shake well, and if transparent it is fit for use, if not, add sufficient alcohol, shaking it well, to bring it to the natural colour of the alcohol. It may be coloured to suit the fancy by adding a little tincture of golden seal, or any other colouring drug. This receipt has been sold for $10.
28. BURNING FLUID
Take 4 quarts alcohol, and 1 quart spirits of turpentine; mix well together, and it is ready for use.
29. NON-EXPLOSIVE BURNING FLUID
Take 1 gallon 44 proof alcohol, 1 quart camphene, 3 oz. of alum pulverized, 1/2 oz. camphor gum, 65 drops cuicuma; mix all together and let it stand 12 hours, and it is ready for use.
30. VINEGAR IN THREE DAYS WITHOUT DRUGS
Take 2 barrels and saw one of them in two in the centre, and put one-half on the top, and the other at the bottom of the whole barrel, (or you may use three whole barrels if you like.) The middle barrel is to be filled with maple, beech, of baswood shavings, which are to be planed from the edge of boards only two or three feet long, which allows the shavings to roll, and prevents them from packing tight, and also allows air to circulate through them, which is admitted through a number of inch holes, which are to be made near the bottom of the barrel and just above the faucet, which lets the vinegar run into the tub below. The top tub has its bottom pierced with small bit holes, having several threads of twine hanging in them to conduct the vinegar evenly over the top of the shavings in the middle of the barrel. Air must be permitted to pass out between the top tub and barrel, which comes in at the holes in the bottom. The shavings which fill the barrel must be soaked three or four days in good vinegar before they are put in. When thus arranged, for every gallon of water use 1/2 lb. of sugar; (that you get from molasses barrels does vary well.) If you wish to make vinegar from whiskey, put in 4 gallons of water to 1
