346. Ground Glass. The frosted appearance of ground glass may be very nearly imitated by gently dabbing the glass over with a paint brush dipped in white paint or any other oil colour. The paint should be thin, and but very little colour taken up at one time on the end of the bristles. When applied with a light and even touch the resemblance is considerable. 347. Oiling Clocks. Family clocks ought only to be oiled with the very purest oil, purified by a quart of lime water to a gallon of oil, in which it has been well shaken, and suffered to stand for three or four days, when it may be drawn off. 348. Neat Mode of Soldering. Cut out a piece of tinfoil the size of the surfaces to be soldered. Then dip a feather in a solution of sal ammoniac, and wet over the surfaces of the metal, then place them in their proper position with the tinfoil between. Put the metals thus arranged on a piece of iron hot enough to melt the foil. When cold the surfaces will be found firmly soldered together.
