(1) If was used to imitate Josiah Wedgwood's rosso ant-leo and black basalt stoneware and was often decorated.(2) Instead there was just a headstone of black basalt .(3) Some are made up of dense, black, homogeneous basalt , with no visible mineral grains.(4) Wedgwood's basalt , a hard, black, stone-like material known also as Egyptian ware or basaltes ware, was used for vases, candlesticks, and realistic busts of historical figures.(5) Further east is Diyarbakir, a sultry place, where groups of Kurds lurk on the street corners and the black basalt of the walls and the cobbles fill the alleys with its funereal tones.(6) The fine-grained basalt stoneware reflected Wedgwood's Neoclassicism.(7) One of the leading glass makers of the early 19th century classical revival in Bohemia was Count Von Buquoy, who, in 1817, successfully produced an opaque black glass that resembled Josiah Wedgwood's black basalt stoneware.(8) When wet, the basalt changes colour from silvery grey to gleaming black.(9) At ground level, a bistro and book shop have been elbowed aside to create a senselessly spacious foyer, floored in black basalt .(10) With walls of black basalt and ice rising 300 metres on each side of the narrow channel, this impression - of cruising through a high mountain valley - is not far from the truth.(11) Some areas of this lava formation are highly mineralized, whereas other equally large areas are hard, solid black basalt without any minerals.(12) On one face of the stone, a tablet of extremely hard black basalt , there is a long trilingual inscription; the three texts begin written one above other.(13) There are rare dykes with compositions similar to ocean-island basalts .(14) Also of interest in the area is a basaltic column by the sea near Owenga.(15) To the east was the thin crust of soil that covered the great basaltic flows of the Great Basin.(16) Thick sequences of basalts form the Morgedal and Gjuve formations and include series of sub-aerial lava flows.
