3282 This Albumenized Paper possesses the advantage of giving prints of 

 extraordinary softness and brilliancy of tone, the photograph being on the 

 surface, and not in the body of the paper, as is the case with the ordinary quality.

DIRECTIONS FOR USE OF FORMSTECHER'S DIAMOND ALBUMENIZED PAPER. 



The Sensitizing Bath. Nitrate of Silver, 1 ounce, Distilled Water, 10 ounces-. 

 If used stronger it drains unevenly from the paper. Floating should not be less 

 than four minutes for thin, and five minutes for thick paper, otherwise the salting 

 will not be completely converted into Chloride of Silver or the Albumen coagulated ; 

 and if this is not the case, the albumen partially dissolves in the subsequent 

 washing, producing flat and spotty results. Prolonged floating has no injurious 

 effects. The temperature of the bath ought not to be less than 66 Fah. 



The sensitized paper should not be allowed to curl, or the surface will crack ; 

 it should be kept perfectly flat. 



The paper will tone with any of the recognised formulae, but the Chloride of 

 Lime is recommended, which may be used a longer time than the ordinary baths, 

 by adding additional gold as required. The prints should be washed in the usual 

 way before toning. 



The Toning Bath, No. 1. Chloride of Gold, 15 Grains, Distilled Water, 

 10 drachms. No. 2. Chloride of Lime, half ounce ; water, 40 ounces. 



Take one ounce of No. 1, the same of No. 2, half a teaspoonful of chalk or 

 whiting, and water 18 ounces ; shake well and let stand three or four days, then 

 filter for use. When the bath is exhausted, add more of No. 1, and a little chalk 

 to neutralize the gold. No. 2 must seldom be added, and then only in small 

 quantities, as an excess is injurious, producing cold grey tones and a bleaching 

 effect. 



The Fixing Bath. Hyposulphate of Soda, one ounce, and Water, one pint. 

 A weak solution is recommended, the fixing being equally perfect. A stronger 

 solution tends to blistering. It is most important that all the solutions and washing 

 waters should be the same temperature TO"* 1 Fah. Higher or lower temperature 

 is apt to produce blisters, which are better avoided, although of little consequence 

 in the finished picture. One ounce of common salt to one pint of water in the 

 first washing water is a remedy against blistering.
