The red coloring matter gave much confusion to the ancient writers generally. The term cinnabar (KnW/fapts) was used to indicate the blood-red resin, dragon s blood, and by Theophrastus for our cinnabar. The term, minium was used by later writers for our cinnabar, but often also for red lead, and evidently the users did not know how to distinguish between them. 

Spain, is mixed with silver-sand. Elsewhere it is not known. When heated in the furnace, it turns to a brilliant flamelike color. The vapor it gives off is suffocating. It is used by painters. This description leaves room for doubt as to whether red lead or cinnabar is referred to. But the real cinnabar, he goes on to explain, is the red resin, Dragon s blood. 

Arsenikon and sandarach mean to Dioscorides, as to Theophrastus, respectively orpiment and realgar. The former, yellow scales or plates, is used in medicine as a depilatory and a caustic. Heated alone, or with charcoal, it loses color and leaves a mass which cooled and powdered is a deadly poison (arsenious oxide). Curdled milk is said to be an antidote. Sandarach, red like cinnabar (dragon s blood, he means), behaves when heated like arsenikon, and in general has properties similar to that substance. He notes that it gives a sulphureous odor when roasted. 

Some natural dyes are coming back into use and amongst these is one called Dragon s Blood (C.I. Natural Red) which consists of the flavenes dracorhodin (134) and dracorubin (135). 

Little used today is Dragon s blood, an oleoresin obtained from the fruits of Daemonorops draco, a native palm of southeastern Asia and the Molucca Islands The resins exudes from the surface of the ripening fruits. It is removed from them by boiling in water, The resin is then moulded into balls or long sticks. It is sometimes used in making varnishes and lacquers. 

The coloured materials most frequently added are gamboge, dragon s blood, turmeric, indigo, and especially artificial organic colouring matters. For some varnishes mineral colours are used, such as ferric oxide, white lead, minium, lamp black, etc. 

Cinnabar and vermilion usually contain only small proportions of impurities from the prime materials vermilion may also contain impurities due to the method of preparation, namely, small quantities of metallic mercury, mercuric nitrate and free sulphur. These products are, however, often adulterated with ferric oxide, minium, chrome red, brickdust, gypsum, heavy spar, clay, ammonium chloride, dragon s blood, carmine and artificial organic dyes. Sometimes also arsenic and antimony sulphides are added to modify the colour. 

Although benzoic acid occurs naturally in some substances, such as gum benzoin, dragon s blood resin, balsams, cranberries, and the urine of the ox and horse, the product is made on a large scale by synthesis from other materials. Benzoic acid can be manufactured by the liquid-phase oxidation of toluene by air in a continuous oxidation reactor operated at moderate pressure and temperature ...
