Speculative chemistry The science by help of which the substance thinkers of medieval occasions endeavored to transmute the baser metals into gold or silver. There is impressive difference of assessment with regards to the historical underpinnings of the word, however it would appear to be gotten from the Arabic al=the, and kimya=chemistry, which thusly gets from the late Greek chemica=chemistry, from chumeia=a blending, or cheein, 'to spill out' or 'blend', Aryan root ghu, to pour, whence the word 'spout'. Mr. A. Wallis Budge in his Egyptian Magic, in any case, expresses that it is conceivable that it might be gotten from the Egyptian word khemeia, in other words 'the arrangement of the dark mineral', or 'powder', which was viewed as the dynamic rule in the transmutation of metals. To this name the Arabs joined the article 'al', in this way giving al-khemeia, or speculative chemistry. HISTORY OF ALCHEMY: From an early period the Egyptians had the notoriety of being able specialists in metals and, as indicated by Greek scholars, they were acquainted with their transmutation, utilizing mercury during the time spent isolating gold and silver from the local framework. The subsequent oxide should have grand forces, and it was imagined that there dwelled inside in the distinctions of the different metals, that in it their different substances were joined. This dark powder was supernaturally related to the black market type of the god Osiris, and thusly was credited with enchanted properties. In this manner there experienced childhood in Egypt the conviction that enchanted forces existed in motions and amalgams. Presumably such a conviction existed all through Europe regarding the bronze-working ranks of its few races. Its was most likely in the Byzantium of the fourth century, nonetheless, that catalytic science got undeveloped structure. There is little uncertainty tha t Egyptian custom, sifting through Alexandrian Hellenic sources was the establishment whereupon the baby science was assembled, and this is borne out by the condition that the craftsmanship was credited to Hermes Trismegistus and expected to be contained completely in his works. The Arabs, after their triumph of Egypt in the seventh century, carried on the explores of the Alexandrian school, and through their instrumentality the workmanship was brought to Morocco and hence in the eighth century to Spain, where it prospered exceedingly. Surely, Spain from the ninth to the eleventh century turned into the store of catalytic science, and the schools of Seville, Cordova and Granada were the focuses from which this science emanated all through Europe.
