SILVERING GLASS AT HOME 



liY A. J. JARMAN. 



A GOOD glass mirror, made with one's 

 own hands, is a thing to be proud 

 of. Mirrors are now seldom made 

 by the tinfoil and mercury process, because 

 of the dangerous character of the work, but 

 pure silver is used instead. The silver pro- 

 cess is not in the least dangerous to the 

 workman. The formula here given is one 

 that has been in use in several looking glass 

 and art mirror factories in the city of Lon- 

 don. The chemicals used must be of ab- 

 solute purity (chemically pure) and all 

 operations in preparing the glass must be 

 carried out with care and scrupulous clean- 

 liness. The surface to be silvered must not 

 be pressed upon by the rtngers or thumbs, 

 tlicy would leave an indelible impression. 



The first thing to be done is to make a 

 small table out of a piece of slate about ^ 

 or y2 inch thick, 10 or 12 inches wide and 

 18 inches long. These measurements are 

 not binding, any piece of slate about the 

 above size will do. A wooden trough must 

 be made with groves at the top edges for 

 the slate slab to rest in. There must be a 

 space of 2 inches between the slate slab to 

 the wooden bottom, as indicated in Fig. 1. 

 In this space is a coil of pipe arranged as 

 shown in Fig. 2. The pipe is of about ^ 

 inch bore, and through it steam is passed to 

 raise the temperature of the slate slab to 

 about 120 deg. F., in fact just hot enough 

 for the hand to bear. The steam can be 

 supplied from an ordinary tea kettle placed 

 near the depositing table with a rubber tube 

 connecting the coil to the spout of the kettle. 

 Uniform heating of the slate slab is essen- 

 tial. The coil can be easily made of i4"ii^ch 

 iron gas piping, screwed into U-shaped cast- 

 iron connectors, as shown in Fig. 2. The 

 slate slab can be covered with black oilcloth 

 and made perfectly level. The following 

 stock solutions must be made up and care- 

 fully filtered through absorbent cotton, 

 ready for use : 



Stock Solution A. — Nitrate of silver, 3 

 ounces ; distilled water, 10 ounces ; strong 

 water ammonia, 12% ounces. This solu- 

 tion must be stirred well and allowed to 

 stand five or six hours, then add 10 ounces 

 more of distilled water and filter. 



Stock Solution B. — Rochelle salts, 4 

 ounces ; distilled water, 20 ounces. 



Stock Solution C. — Distilled water 40 

 ounces, protochloride of tin, 5 grains. 



Clean the glass plate or plates with very 

 fine rouge and water, taking care that no 

 trace of grease whatsoever comes into con- 

 tact with the glass or the cloths or chamois 

 leather used for polishing. When cleaned, 

 the plate must be flooded all over with the 

 tin solution. Pour this solution off and 

 wash the plate well with distilled water. 

 Lay the plate wet side up upon the table, 

 with four clean wood wedges at each 

 corner. Let the glass rest on the wedges, so 

 as to allow a slight adjustment, if required, 

 for leveling. The mixture for silvering is 

 made up as follows : 



Distilled water, 20 ounces ; stock solu- 

 tion B, 1 drachm by measure ; stock solu- 

 tion A, 1 ounce by measure. The glass 

 plate being quite level, and still wet, pour 

 this mixture carefully and slowly upon the 

 center. It will flow evenly all over until it 

 stands about one-eighth of an inch deep all 

 over the plate. Any tendency to run to one 

 end must be rectified by the wedges. The 

 plate now being completely covered with 

 the silvering mixture must be left to itself 

 for about two hours, the heat being kept up 

 during this time, and when it is found that 

 the whole of the silver has been deposited, 

 the liquid must be poured ofif by tilting and 

 allowed to run into a stoneware crock and
