What a great resource Richard. Thank you. I didn't know about the process for the reflective hematite. You learn something new every day! Also, my first geology book was a Lyell's Principles. I'll have to check but I think it is a mid-1800s edition (single fat volume).

8th Edition 1850. Sadly, no hand-coloured plates in this one.
