How bricks were arranged to build walls in harappan cities?
Answers
Interlocking pattern of laying bricks was used while building walls in Harrapan cities. Ancient Indus valley civilization was known for the strength of its walls which stood strong for thousands of years. These bricks were watertight due to the presence of natural tar and coated with plaster for extra strength of the walls.
Answer:
Brick made today is very inexpensive. Brick made in the Bronze Age was made by hand, so it was not inexpensive. The IVC brick represented technological advances, so significant effort was placed in improving it. This also is a cost we don't spend when we use brick, because brick never fails due to our lack of understanding in the best way to make it or to use it. There is some evidence, the IVC may have been transporting the bricks between towns. This is the reason the bricks are the same. The IVC domesticated the elephant and were among the first to develop an efficient type of wheeled transport. Transporting bricks is not any easier than moving stone from a quarry.
Over centuries time and the usage of bricks was perfected it probably became less expensive. When it was first being developed, it was probably more expensive. Therefore, the cost is not likely to be the reason the IVC are using brick, but rather that it represented significant advantages for them.
