Original Note:
Ancient Egyptian pyramids, both at Giza and elsewhere, did not look as sandy brown as they do now. Rather, they were covered in a layer of glossy sedimentary rock. The casing would have provided the pyramids with a smooth, polished covering that shone under the Sun. https://www.sciencetimes.com/articles/42229/20230206/ancient-egyptian-pyramids-covered-shiny-white-limestone-thousands-years-ago.htm
