Page 187 - I confess myself of opinion that there can be no precise rules drawn from the appearance of the stones before, for that which they will assume after burning, because it depends partly on the degree of heat they undergo. A red cornelian by an intense heat will become white ; but as far as my observations go, no stone of the former colour is found so in the mines (excepting jaspers,) although a large proportion of them assume it at Neemoodra. Many also after having been burnt show both colours, sometimes...
Page 187 - ... at Baroach, who was formerly in the cornelian trade, and had himself superintended the process at Neemoodra; his account is corroborated by our personal observation, and by what we learned on the spot. The stones are brought to this village every evening, spread on the ground, exposed to the sun to prepare them for the further process, and turned every fifteenth day till the time of burning, which is only once a year ; one month before the commencement of the, monsoon. They are then put into...
Page 188 - E2 the pieces taken from the bottoms are put inside and placed over the mouths to prevent the stones falling out ; in this state the pots are placed side by side in a trench of indefinite length, but of which the depth and breadth are about two feet, having a layer of five or six inches of dry goats' dung below, and the same above the pots.
Page 187 - I saw none imbedded in rock, as flints are in chalk ; some nodules on being broken showed a mixture of quartz and agate, and others, in a crust of quartz minutely crystallized on the inner surface, contained a black oxide of iron of a powdery appearance, many pieces of which we found by itself in the gravel. Hematites, chiefly of the brown and green (with red spots) varieties, mocha stones, and jaspers of various colours, are very common here ; indeed the last was found in almost every part of the...
Page 187 - Many also after having been burnt show both colours, sometimes distinct and sometimes mixed, and of a pinky hue ; while the colour was uniform, or very nearly so, in all which I remarked at the mines. The lightest-coloured stones come out of the fire of a much more delicate and transparent white than before, and often surrounded by a cortex of red, but without any distinct line separating the colours. We were unfortunate in the time of visiting Neemoodra, for all the good stones had been removed,...
Page 175 - August full moon) they offer flowers and cocoanuts at his tomb. As it is far to go from Cambay to Bawaghor, they have in Cambay a cenotaph takiya in his honour, and those of them who are settled in Bombay have brought with them this memorial of the founder of their craft. The Cambay agate workers assert that the well-known shrine of Bawaghor was raised in honour of their patron. According to their story, while wandering from place to place as a religious beggar, the Bhawa did business in precious...
Page 187 - The soil is gravelly, consisting chiefly of quartz sand reddened by iron, ami a little clay. The nodules may weigh from a few ounces to two or even three pounds, and lie very close to each other ; but for the most part distinct, not in strata, but scattered through the mass, and in the greatest abundance. I saw none of a red colour at the, mines ; some were blackish olive like common dark flints, others somewhat lighter ; and others lighter still, with a slight milky tinge. The first, our guide informed...
Page 175 - Cambay a cenotaph, lakiya, in his honour, and those of them who are settled in Bombay have brought with them this memorial of the founder of their craft. The Cambay agate workers assert that the well known shrine of Bawa Ghor was raised in honour of their patron. According to their story, while wandering from place to place as a religious beggar, the Bawa did business in precious stones, and, becoming skilled in agates, set up a factory at Nimodra. Here he prospered and died rich.
Page 177 - ... a rosy tint, orange is intensified into red, and an intermediate shade of yellow becomes pinkish purple. Pebbles in which cloudy browns and yellows were at first mixed are now marked by clear bands of white and red. The hue of the red carnelian varies from the palest flesh to the deepest blood-red. The best are a deep clear and even red, free from cracks, flaws, or veins. The larger and thicker the stone, the more it is esteemed. White carnelians are scarce. When large, thick, even-coloured,...
Page 16 - Naniazeik as well as in the river-gravels on the eastern slope.s of the mountain ranges between Naniazeik and Manwe. This mountain range is composed mainly of granite and crystalline limestone, the latter having obtained its crystalline characters probably as stated before, through the intrusion of the granite. The limestone contains various minerals as the result of contact-metamorphism — garnet, spinel, chondrodite, graphite, forsterite, and other accessories, besides the valuable rubies and...
