(1) To clean glass in frames, when the latter are covered or otherwise so finished that water cannot be used, moisten tripoli with brandy, rub it on the glass while moist, and when dry rub off with a silk rag; to prevent the mixture injuring the cloth on the frame, use strips of tin bent to an angle; set these on the frame with one edge on the glass; when the frames are of a character that will not be injured by water, rub the glass with water containing a little liquid ammonia, and polish with moist paper.

Cleansing Glass Bottles

(2) If vessels are oily or otherwise greasy, they should not be washed with water, but wiped with dry tow, or a dry dirty cloth, so as to remove as much grease as possible. By changing the cloth for one that is clean, the vessel can be wiped until all traces of grease disappear. (3) A strong solution of an alkali, such as pearlash, may be used, whereby the removal of the frease is materially facilitated. (4) If a vessel be soiled by resin, turpentine, resinous varnishes, etc, it should be washed with a strong alkaline solution, and rubbed by means of the wire and tow. (5) If the alkali fail to act, a little sulphuric acid may be employed with advantage. The latter acid will also be found advantageous in removing pitch and tar from vessels of glass. .Nitric or sulphuric acids may be employed to clean flasks which have contained oil. (6) A correspondent of the Philadelphia Photographer says: - "To clean a silver-bottle, pour in a strong solution of cyanide; shake a few times, pour out, and rinse with water 2 or 3 times, and your bottle is perfectly clean. Keep the solution, and filter and strengthen when required.

By doing this you can sun your bath better in 2 hours than in a week's exposure in the dirty black bottles photographers appear to delight in." (7) It would be easy for a practical brush-maker to construct a brush, in the form of a hollow cone, which would reach the bottom of bottles; but the difficulty would be to get it into the bottle without spoiling it (the brush). A brush composed of a single bundle of long hairs (something like a painter's sash-tool) with the bristles cut somewhat tapering, should answer the purpose. The bottle must, of course, be turned round with the hand, to bring every part into contact with the brush.

(8) Lead shot, where so used, often leaves carbonate of lead on the internal surface, and this is apt to be dissolved in the wine or other liquids afterwards introduced, with poisonous results; and particles of the shot are sometimes inadvertently left in the bottle. Fordos states that clippings of iron wire are a better means of rinsing. They are easily had, and the cleaning is rapid and complete. The iron is attacked by the oxygen of the air, but the ferruginous compound does not attach to the side of the bottle, and is easily removed in washing. Besides, a little oxidized iron is not injurious to health. Fordos found that the small traces of iron left had no apparent effect on the colour of red wines; it had on white wines, but very little; but he thinks it might be better to use clippings of tin for the latter.

(9) Take a handful of common quicklime, such as bricklayers use, and a handful of common washing soda; boil them in a large kitchen iron saucepan (which will only be cleaned, not damaged, by the process). When cold, the fluid will be soap lye; put this into the vessel you want to clean with some small pebbles or shot; make it warm if you can, and shake up or let it soak according to the nature of said vessel. (10) Glass vessels are cleaned with sand, or shot, which are objectionable. Gypsum without silicate, marble, bruised bones, are preferable. Sulphuric acid and bichromate mixed, are best to free porcelain and glass from organic matter. (Eng. Meek.)

(11) Glass Bottles Which Have Contained Petroleum

Wash with thin milk of lime, which forms an emulsion with the petroleum, and removes every trace of it; by washing a second time with milk of lime and a small quantity of chloride of lime, even the smell may be so completely removed as to render the vessel, thus cleansed, fit for keeping beer in. If the milk of lime be used warm, instead of cold, the operation is rendered much shorter. (Ding. Pol, Jl.)

Glass Globes

(9) Rub inside with a little wet pumice-powder on a cloth, and in 2 minutes you would not know that they were not newly purchased. The best way to cleanse dirty glass of all kinds is to put a small quantity of spirits of salts (hydrochloric acid) into a basin of water, and to place the dirty articles in the liquid for a few minutes, when it will be found that the glass is clean, and only requires drying. If very dirty, the globes may require to stay in the liquid a little longer. This plan is very useful for cleaning the pendant drops of glass chandeliers, water bottles, etc, as no soap is required. Care must be taken not to drop the undiluted spirits of salts on the clothes or hands.
