Shah Mosque (Isfahan)
The Shah Mosque is a mosque located in Isfahan, Iran. The Masjed-e Shah was a huge structure, said to contain 18 million bricks and 475,000 tiles. It employed the new haft rangi (seven-colour) style of tile mosaic. In the haft rangi method, artisans put on all the colors at once, then fired the tile. Cheaper and quicker, the new procedure allowed a wider range of colors to be used, creating richer patterns, sweeter to the eye.
