All salts are composed of two parts, of an acid and of a base. To assure myself that the acid of gypsum was that of vitriol, as I naturally presumed it to be, I placed in a small crucible some calcined pierre specu-laire along with some powdered charcoal. As soon as the material became red, the cover of the crucible became surrounded by a small blue flame. When the lid was removed, the surface of the material was seen to be covered with the same flame, and a slight odor of the volatile sul-furous acid could be detected. When the mixture so calcined had cooled, I added some acid to it. Immediately there was disengaged the odor of rotten eggs so that it was easy to identify the presence of liver of sulphur. I remade the same mixture of plaster and of charcoal in adding to it some fixed alkali, there resulted a true liver of sulphur.

The apparatus in the form just described, though capable of concentrating vitriol, cannot be said to be a success. The fusion of the lead in Hie upper portion was tho weak point in this invention in order to work the apparatus with practical efficiency, it was necessary to have the air highly heated, in fact tho current of air may be said to have been red hct. Under these circumstances it was almost impossible to avoid the fusion of tho lead tube which conveyed the hot air from... 

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. 

Green vitriol calcined to drive off the water of crystallization, and brought to n pale red tint, and then well washed until perfectly free from the sulphuric acid. Here great care is required to obtain the proper tint, neither too pale nor too dark. 

Almagra,37 (defined sometimes as a red earth, sometimes as brass, or as copper hole), acimar (that is, flos aeris, copper oxide), Atramentum ustum, roasted vitriol, roasted brass (mixture of copper and zinc oxides), rock salt, almisadir (sal ammoniac), saffron root or saffron itself—equal parts. All these are mixed with urine and dried in the sun. With this powder mix filings... 

Take first one pound of vitriol of Cyprus and a half pound of salpeter and a quarter pound of laminated alum and extract the water at the red heat of the alembic, for the solvent power is great, and make use of it in the fore-mentioned chapters it will be made much sharper if you dissolve with that a fourth part of sal ammoniac, because it then dissolves gold, sulphur and silver. ... 

The separation of the elements from metals is a process in which you should provide yourself with good apparatus, and with experienced manipulation and workmanship. First make an aqua fortis thus take of alum, vitriol, sal-nitri, equal parts, distil to a strong aqua fortis, return that to the residue and distil a second time in a glass flask. Dissolve in this silver and afterwards dissolve in it sal ammoniac. After this is done take the metal in thin plates and dissolve it in the water. When that has taken place separate it in the water bath (balneo mar is), pour it over again until an oil is found at the bottom from gold almost brown, from silver almost bluish, from iron red to almost black, from mercury quite white, from lead lead-colored, from copper quite green, from tin, yellow. 

Many of the ancient authors sing praises to the utility of vitriol. Basil Valentine called it The True Mineral Salt which contains the Red and the White spirits. If vitriol alone is distilled, there will first come over a clear liquid (the White spirit) with a strong sulfur dioxide odor. Keep this tightly sealed and the choking odor will disappear as the dissolved sulfur dioxide oxidizes to form a mild solution of sulfuric acid. As the heat is increased quite high, there will finally ascend a more viscous, reddish liquid which is a concentrated sulfuric acid filled with martial essence (the Red spirit). 

As Mr Blandy s health was deteriorating, a doctor was summoned. He was of the opinion that the patient was being poisoned and that Mary s position would be serious if he were to die. The contents of the soup pan and the white powder were examined by another doctor. Dr Addington, who carried out a series of tests and compared the results with those of a known sample of white arsenic. These tests were very thorough and included adding the powder to water, sprinkling it on red-hot iron, and adding various other substances such as syrup of violets and spirit of vitriol to a solution of the sediment. The doctor observed an exact similitude between the results with the sediment and the known sample of arsenic oxide. 

The acid of sulphur was precisely the same as that of vitriol and alum, as Homberg had earlier predicted. It produced alum with simple earth, vitriol with an earthly and a metallic matter, and common sulphur with an earthly and a bituminous or inflammable matter. Homberg believed that the second component, a dense, bloody red oil, was the true sulphur or the inflammable part of common sulphur, carried in the minimal amount of distilled oil which served as a vehicle. The sulphur principle still eluded him, however. The third component, an earth, was extremely fixed (having lost the volatile component of oil) and nearly inalterable. Even when exposed to the burning glass, it only produced fumes without burning.
