This name was derived from the town of Javelie, in France, where a manufactory sold a liquor which had the property of bleaching cloth by an immersion of some hours only. The following is the original recipe given by Gray in his " Oper-Itive Chemist": 2 1/2 lbs. common salt, 2 lbs of sulphurio acid, and 1 lb. of black manganese are mixed in a retort and heated, and the gas which comes over is condensed in 2 gallons of water in which 5 lbs. of potash have been dissolved. This liquor is diluted with twelve times its bulk of water.
This process is available only by chemists, however. The following gives good results: Take 4 lbs. carbonate of soda, and 1 lb. chloride of lime; put the soda into a kettle, add 1 gallon of boiling water and boil for from 10 to 15 minutes; then stir in the chloride of lime, breaking down all lumps with a wooden spatula or stirrer. Pour into large glass bottles; when cold and settled it will be ready for use.
This forms a very efficient bleaching liquid and one which it is not difficult to remove from the bleached fabric. Old and stained engravings and books, as well as linen and cotton goods that have become yellow with dirt and age, may be rendered snowy white by the application of this liquid.
