The 2nd edition has been out of print since June 2024. Because I received so many requests for the 2nd Edition I have had it reprinted for the 21st time. The 1st edition is a 94-page description of the modern manufacturing process. The 2nd edition is a 470-page hard-cover book that contains the 1st edition plus and expansion that has historical and product information. I have sold many to Photrio Members.
I'll attach a few scans of pages from the 1st edition. These and many more are in the 2nd edition.
Ooo intriguing!! I just started a black and white class and we’re getting into the technical chemistry side a lot more than my other class so I’m going to check out your site. Book looks awesome.
