This book is discussed in detail on this video – link here.

I will update this post shortly, but just wanted to start by making sure the XRF readings were up online. Readings are science-based, replicable and accurate. Each component of each piece reported on (here on this blog) has been tested multiple times to confirm the readings and one full set of readings (per component) is reported here on the blog.

Thank you for reading and for sharing my posts!

Please let me know if you have any questions.
