ديالكتيك الأبنوس والنمل الأبيض - قناة Ebony وحتمية الوحدة

Quote: Uses Ebony has a long history of use, with carved pieces having been found in Ancient Egyptian tombs. The word "ebony" derives from the Ancient Egyptian hbny, via the Ancient Greek ἔβενος (ébenos), by way of Latin and Middle English. By the end of the 16th century, fine cabinets for the luxury trade were made of ebony in Antwerp. The dense hardness lent itself to refined moldings framing finely detailed pictorial panels with carving in very low relief (bas-relief), usually of allegorical subjects, or scenes taken from classical or Christian history. Within a short time, such cabinets were also being made in Paris, where their makers became known as ébénistes, which remains the French term for a cabinetmaker. Modern uses are largely restricted to small sizes, particularly in musical instrument making, including piano and harpsichord keys, violin, viola, guitar, and cello fingerboards, tailpieces, pegs and chinrests. Traditionally, black piano and harpsichord keys were ebony, and the black pieces in chess sets were made from ebony, with rare boxwood or ivory being used for the white pieces. Modern east Midlands-style lace-making bobbins, also being small, are often made of ebony and look particularly decorative when bound with brass or silver wire. Due to its strength, many handgun grips, and rifle fore-end tips, are made of ebony as well. Many plectrums, or guitar picks, are made from this black wood. In Dakshina Kannada and Udupi districts of Karnataka (India), the tree is called Karmara in the native Tulu language. Ebony tree forests which once covered large areas of these districts have shrunk significantly due to rapid urbanization. The wood of ebony is used as firewood, as it can burn even in moist conditions. As a result of unsustainable harvesting, many species yielding ebony are now considered threatened. Africa in particular has had most of its indigenous ebony cut down illegally and as such it has become common for street traders to color lighter woods black with shoe polish in an effort to make a sale.
