Bricks made without straw would break and crumble easily. Adobe bricks used around the world are generally only sun dried but grasses, straw and other materials are added to the clay for the same basic reasons. [3] The ancient brick-making process can still be seen on Egyptian tomb paintings and models.
Diorite is an intrusive igneous rock composed principally of the silicate minerals plagioclase feldspar (typically andesine), biotite, hornblende, and sometimes pyroxene.The chemical composition of diorite is intermediate, between that of mafic gabbro and felsic granite.
In general, it seems that the clay came from three different places: the shore of the Nile or irrigation canals, the desert near the fields, and the hills of the desert itself. A depiction in the tomb of Rekhmire shows workers in the process of building up pile of Nile mud with hoes in order to make mudbricks. Clay for pottery production might ...
Rock temples cut directly in the rocks at the Silsileh quarrying site, near Aswan. The stone quarries of ancient Egypt once produced quality stone for the building of tombs and temples and for decorative monuments such as sarcophagi, stelae, and statues. [1]
A brick-lined well is a hand-dug water well whose walls are lined with bricks, sometimes called "Dutch bricks" if they are trapezoidal or made on site. The technique is ancient, but is still appropriate in developing countries where labor costs are low and material costs are high.
Large bricks on a conveyor belt in a modern European factory setting. A brickworks, also known as a brick factory, is a factory for the manufacturing of bricks, from clay or shale. Usually a brickworks is located on a clay bedrock (the most common material from which bricks are made), often with a quarry for clay on site.
Lego has abandoned plans to make its famous bricks from recycled plastic bottles, saying that the manufacturing process would be more polluting than the current production of oil-based bricks.
The remnants of a very large diorite statue in the British Museum may be a representation of Gudea, but this cannot be determined with certainty. What remains of the statue is 1.5 m (4 ft 11 in) high (and weighs over 1,250 kg (2,760 lb)), meaning that if it were fully reconstructed the statue would be well over 3 m (9.8 ft) high and the largest ...
