It must be borne in mind when reviewing the theories of the alchemists, that there were a number of phenomena known at the time, the superficial examination of which would naturally engender a belief that the transmutation of the metals was a common occurrence. For example, the deposition of copper on iron when immersed in a solution of a copper salt e.g., blue vitriol) was naturally concluded to be a transmutation of iron into copper, although, had the alchemists examined the residual liquid, they would have found that the two metals had merely exchanged places and the fact that white and yellow alloys of copper with arsenic and other substances could be produced, pointed to the possibility of transmuting copper into silver and gold. It was also known that if water (and this is tme of distilled water which does not contain solid matter in solution) was boiled for some time in a glass flask, some solid, earthy matter was produced and if water could be transmuted into earth, surely one metal could be...

Copper Sulphate Pentahydrate. Calculate what amount of copper sulphate crystallohydrate (blue vitriol) has to be taken for 10 ml of water to prepare a solution saturated at60°C (see Appendix 1, Table 1). Bring the solution obtained at the indicated temperature almost up to boiling and rapidly filter it through a fluted filter on a funnel for hot filtration (the funnel must be hot). Close the test tube with the filtrate with a piece of cotton wool. If crystals have formed in the filtrate, dissolve them by careful heating. Cool the solution and introduce a minute crystal of the initial salt into it. What is observed Does the temperature of the solution change ... 

Oxides of Copper—red oxide of copper—Cu, 0—is prepared by heating one hundred parts of blue vitriol with fifty-seven parts of carbonate of soda until the water of crystallization Is expelled. The rosiduum is afterwards mixed with twenty-five parts of copper filings, and the mixture finely stamped into a crucible. It iB then exposed to a white boat for about twenty minutes, and after cooling and pulverization, the mass is well washed with water. ThiB process yields about fifty parts of fine colored red oxide of copper. 

Chalcanthon (Latin chalccmthum) is evidently used by Dioscorides to designate the sulphate of copper (blue vitriol), and also to include mixtures of sulphates of copper and iron, or even the sulphate of iron itself (green vitriol). The best, he says, is blue and transparent, and obtained by evaporation to blue crystals, but also it is obtained as... 

The value of chalcanthum in coloring leather black, doubtless in conjunction with tannin, would depend upon the iron present, and as both Dioscorides and Pliny refer to variations in color of different grades of chalcanthum, it is evident that both green and blue vitriol and mixtures of the two passed under that designation. 

It will be recalled that the chalcanthum of Pliny and Dioscorides was either blue vitriol, green vitriol or apparently more commonly a mixture of the two, obtained by the weathering of wet iron or copper-pyrites. The above specifications would appear to recognize these varieties of flowers of copper. Some specimen recipes will perhaps convey a more adequate understanding of the processes employed.

Lab grade hematite (Fe203) and copper sulfate (anhydrous and hydrated) were mounted on slides and used as controls to compare to mineral deposits that might have been found adhering to foe fibers. Rabbit hair and milkweed that had been colored with an aqueous hematite solution and with an aqueous copper sulfate (blue vitriol) solution were also used for comparison. Fibers removed from each simulated material were mounted in water (Refractive Index (Rl) of 1.0), and in Permount (Fisher Scientific) (RI of 1.55). The collected particulate matter and fibers removed from foe yam samples were similarly mounted and examined using optical microscopy. 

The problem is to do optimization of the zinc ore floatation procedure, in a lab plant. The system factors are xj-pressure of gas for barbotation of pulp, at x2-time of extraction under pressure, min x3-consumption of butylxanthogenate, g/t and x4-consumption of blue vitriol, g/t. As system response, these parameters have been measured y,-quality of concentrate, % and y2-percentage of separation, %. The outcomes of simplex optimization are given in Table 2.220. 

Copper sulfate (CuS04) is the most important compound of copper, and is commonly known as blue vitriol. 

Second It follows the law of definite proportions, for example, every sample of blue vitriol which has been crystallized from water at room temperature has exactly the composition expressed by the formula CuS04-5H20. (The next experiment is a quantitative one designed to prove that a crystal hydrate has a definite composition.)... 

Heating blue vitriol increases its aqueous tension, and thus the dehydration by heating is in fact an artificially induced efflorescence.
