Roman purple

Another ancient dye is the deep blue indigo [482-89-3], the presence of two bromine atoms at positions gives the dye Tyrian purple [19201 -53-7] once laboriously extracted from certain sea shells and worn by Roman emperors. [Pg.419]

Indigoid dyes represent one of the oldest known classes of dyes. For example, 6,6 -dibromoindigo [19201 -53-7] (44) is Tyrian Purple, the dye made famous by the Romans. Tyrian Purple was so expensive that only the very wealthy were able to afford garments dyed with it. Indeed, the phrase "bom to the purple" is still used today to denote wealth. [Pg.280]

Tyrian Purple was the most expensive and rare dye of the ancient world principally because only a small amount of dye could be obtained from each moUusk, roughly 0.12 mg (95). It was always considered a color of distinction and restricted to regal and ecclesiastical uses ia the Eastern Roman Empire, the heir to the throne at By2antium bore the proud name Porphjro-Genitur, bom to the purple. The Hebrews used purple ia many decorations of the Tabernacle (23). [Pg.401]

The magnificent purple pigment referred to in the Bible and known to the Romans as Tyrian purple after the Phoenician port of Tyre (Lebanon), was shown by P. Friedlander in 1909 to be 6,6 -dibromoindigo. This precious dye was extracted in the early days from the small purple snail Murex brandaris, as many as 12000 snails being required to prepare 1.5 g of dye. The element itself was isolated by A.-J. Balard in 1826 from the mother liquors remaining after the crystallization of sodium chloride and sulfate from the waters of the Montpellier salt marshes ... [Pg.793]

Ancient artisans were able to confer special colourings to their artefacts by applying particular techniques and treatments, which were lost in later centuries. They were also able to give copper based alloys the appearance of precious metals. Some of these special methods have been discovered and identified on ancient objects. The most famous of these alloys in Roman times was certainly Corinthian bronze, a copper alloy containing small amounts of precious metals, which acquired a purple-black or blue-black patination... [Pg.455]

They found eager customers in Egyptians and Etruscans, and later among the Greeks and Romans. Jewish traditions accorded Tyrian purple an important place, and there are several Biblical references to it. The demand for the dye exceeded the supply for centuries, guaranteeing that the price was always high. At times... [Pg.143]

Dyes are intensely colored compounds used in fabrics, plastics, inks, and other products. Dyes were originally extracted from plants or animals and used to color cloth. For example, red carmine (page 2) was extracted from cochineal insects, and blue indigo (the dye used in blue jeans) was extracted from plant material. Both of these dyes are now synthesized in large quantities. The Romans extracted the indigo derivative Tyrian purple (imperial purple) from a sea snail and used the dye to color the robes of emperors and high-ranking senators. [Pg.702]

Dyes were also prepared from certain marine animals, such as the Tyrian purple (royal purple) color used by the Roman emperors. Production of these dyes was very limited in quantity and they were very expensive. Only a limited amount of material could be made from the collected shelled animals. This typically was reserved for royalty and persons of rank. [Pg.176]

The blue dye indigo, derived from the plant Indigofera tinctoria, has been used in India for thousands of years. Traders introduced it to the Mediterranean area and then to Europe. Tyrian purple, a natural dark purple dye obtained from the mucous gland of a Mediterranean snail of the genus Murex, was a symbol of royalty before the collapse of the Roman empire. Alizarin, a bright red dye obtained from madder root Rubia tinctorum), a plant native to India and northeastern Asia, has been found in cloth entombed with Egyptian mummies. [Pg.988]

The use of bromine can be traced back at least to the Roman Empire, whereby the purple togas that were worn by Roman emperors was dyed with bromine that was extracted from sea snails. [Pg.202]
