Whittle, K. (2016). An interview with Tonio Andrade, author of Gunpowder Age. [online] Princeton University Press Blog. Available at: http://blog.press.princeton.edu/2016/04/30/an-interview-with-tonio-andrade-author-of-gunpowder-age/ [Accessed 23 May 2018].
This website (from a well-respected and well-known university) provided useful information on the topic of gunpowder. It was well laid out and easy to navigate. The site was updated in 2018. The interview was with a professor of history at another well-respected university. I looked him up in Wikipedia and found he had written many research papers. The information was reliable as I cross-checked it with Encyclopedia Britannica and it was the subject of a book the professor had also written.
