1. The website that this source is from is http://www.abc.net.au/science/articles/2008/04/21/2223137.htm
2. The author of this source is Jennifer Viegas.
3. The author's credentials are Catharina Blaensdorf scientist from the Technical University of Munich, llaria Bonaduce from the University of Pisa, the Journal of Cultural Heritage, and Erika Ribechini who is a scientist in the Department of Chemistry and Industrial Chemistry at the university of Pisa.
4. This source is different from all the other sources because instead of typing about the history of the Terracotta army, the author talked about the chemical history of the army, like the things used to make the army, the chariots, and buildings. One interesting fact that was quoted by one of the scientists was that when the army was made, it was covered with beaten egg because egg paint is normally very stable and not soluble in water. That made the army less sensitive to humidity and moisture which obviously would and did get underground.
5. I believe my source.
6. I believe this source because this the only website I have come across so far that talks about the chemical and scientific history of the army. In the article were scientific terms that I learned in Biology class.
