Show SYNTHETIC GOLD ACHIEVED SAYS A FRENCH CHEMIST jollivet castelot declares he has made the precious yellow metal with silver as basis paris lias the ages old dream of al chemists of turning baser metals into gold been finally achieved it it has not it soon will be accord ing to M jollivet castelot president of tre society of trench Al chemists who liaa described some of his sue experiments before the as members of the royal acad emy of sciences of belgium 1 I have produced gold from silver mv mav require perfection and other al chemists will perhaps simplify my method i but I 1 am con vinced that the artificial fabrication of gold giai been clearly established and that important consequences can be easily the result of my labors of many years M et castelot told a correspondent the experiments in my laboratory nt deual have given approximately one gram of cold for eiery avent two grams of silver employed synthetic mineral chemistry ahna thus been achieved with alt that it may mean for industrial chemistry in all its branches asked for some technical details concerning his transmutation of metals M showed not the least reticence my experiments hae been carried on since 1008 and have always taken as their point of departure the fact eliat in kiture we find gold associated with antimony arsenic and also with tellurium which Is considered it the mineral izer of the gold therefore seemed logical to intro duce tellurium into the artificial corn which I 1 made of silver arsenical sulphates and antimony this I 1 to added pure silica the mixture i t r ta i i was heated in lay laboratory furnace for one hour at a temperature of 1100 degrees C the result was a grayish black deposit with violet reflects submitted to the action of nitric add the deposit was detached with difficulty small pieces of a greenish metal were obtained the nitric solution decanted there was a greenish yellow taic which was again treated with nitric add and boiled for several hours the liquid was again decanted and the residue which had not been modified w as washed breaud with ammonia and then submitted to the action of aqua regla in which it wis entirely dissolved after several hours of boiling the solution was then subjected 10 tests for gold and showed very ll 11 the presence of gold I 1 thus produced in my laboratory a bronzed go b the intervention of tellurium there was a considerable loss of gold in this experiment as in many eaf ones but it la known that arsenic arsen lc antimony and tellurium involve tm gold in their own fusion and volatilization |
