Hi All

Thinking about Dragons Blood......

The following link Should find a copy of the condensed chemical dictionary. 558 pages (Out of copyright according to the site)

Written in the twenties It is out of date but ideal for locating chemicals both natural and synthetic together with the properties and descriptions of the processes to make them, often with common as well as scientific names that have been forgotten.

**LINK**

As I write this I am downloading a copy quite slowly (should be about half an hour) the progress bar is moving. So be patient. I inherited my paper copy from my fathers library. I remember reading it as a child, Looking for things that go bang. luckily I only read about them.

Regards
John

Have a look at

http://www.tmf.uk.com/metal-coatings.html

for examples of vacuum deposition. They offer services for amature telescope mirror coating and also do gold. It is certainly possible to overcoat aluminium mirrors with a molecular layer of silicon for durability so should be doable for gold.
