Azurite
Collier's New Encyclopedia (1921)
a mineral, called also lazulite; also a brittle, transparent, or subtranslucent mineral, with monoclinic crystals. The luster is vitreous, or verging on adamantine; the color azure-blue, passing into Berlin blue. It is found in England, as also in France, Austria- Hungary, and Siberia. B, b, the second letter and the first consonant in the English alphabet, as it is also in the other languages of the Aryan family spoken in Europe. A sound and and the Greek beta is the second letter and the first consonant in Phoenician, Hebrew, Samaritan, Aramaic, Arabic, and Koptic. In Ethiopic, however, beth stands tenth instead of second in order. Turning next to some of the Aryan languages of Asia, we find that in Armenian be is the 26th of the 38 letters; and in Sanskrit, Mahratta, etc., bu, or ba, is generally placed 23d in the list of consonants, where it is preceded by phu and followed by bha. Returning again to the Semitic, beth, the name given to the second letter of the Hebrew alphabet, is really Aramæan. Like the corresponding word in Hebrew, baith, it signifies a house, to which it has some faint resemblance. blance B is a flat mute, the voice not being so entirely shut off in pronouncing it as it is when one of the sharp mutes, por f, is uttered. The b sound is produced by compressing the lips, a vowel being added to render it audible. It is hence called a labial, from Latin labium a lip, plural Vabia lips; its other associates in the same category being p, f, and v, with which it is often interchanged in the cognate languages. B, as an initial, is used- In designating university degrees: For Latin Baccalaureus, as Artium Baccalaureus Bachelor of Arts B. A. In music: For bass. In chemistry: For the element boron. B, as a symbol, is used- In numeration, in Greek, Hebrew, Arabic, and even occasionally in English, for 2. But B, in Greek, is the diacritical mark for_2,000. In Latin B stands for 300, and B for 3,000. In music: As the seventh note of the diatonic scale. It answers to the Italian and French si. In Germany it is B flat. B
What Has Changed in the Last Century
The mineral is the same one Collier's described in 1921 "azure-blue, passing into Berlin blue" but the entry's naming is now regarded as an error: azurite is a basic copper carbonate, Cu3(CO3)2(OH)2, while lazulite is an unrelated magnesium-aluminium phosphate. Collier's also omits the two things a modern reference leads with, that azurite is a copper ore and a prospector's guide to copper deposits, and that it was the chief blue pigment of European painting before the rise of synthetic blues, which is why so many medieval skies have weathered towards the green of malachite, the mineral azurite alters into. The localities have moved on too: Austria-Hungary no longer exists, and the specimens collectors prize today come from Tsumeb in Namibia, Bisbee and Morenci in Arizona, and Touissit in Morocco. The French locality survives in the old synonym chessylite, after Chessy near Lyon.
