Heavy on the whimsical contemplative artsy stuff - which, don't get me wrong, I also love in moderation - but almost no information on the science behind the inkmaking. In fact, in most of the places where the author tries to say something scientific it's painfully wrong. The worst section is Water. Why only discuss water when some of the recipes involve alcohol? "Additives" are all lumped together in one category that includes things like metal salts, acids and bases but there's little guidance on what to use where, and the recipes do not really elaborate. WHY do clove or wintergreen prevent mold growth? This seems suspiciously too easy and makes no sense to add to a water based ink. Will it not float on the top?? Ugh.
As someone who has done a lot of work with natural dyes over the years and also has a graduate degree in biochemistry, I am continually disappointed at how little interest the natural color communities have when it comes to the science of how these things work, as it could really open up more opportunities for discovery.
"Pigment" has a very different definition in the science world than in the art world and can encompass a wide variety of organic and inorganic molecules that all have wildly different pH, solubility, and stability requirements from one another when it comes to how they interact with cellulose and other substrates. I was hoping to get information on how to make ink that I can use for fine art that is light-fast, stable, will not corrode nibs and paper, or is potentially waterproof. You will not find any information on these things in this book, not any of the science behind these properties. You just have to waste your time blindly experimenting until you get something you like, I suppose.
I will say it made me very excited to go out and forage stuff and experiment, but it seems I'll have to do my own learning when it comes to which pigments need which treatments.
The cherry on top is that he has the line "You are a scientist" when discussing experimenting with the inks. No Jason, no you're not. Science and art both involve creative experimentation, you can take a methodical approach to your art practice, but that doesn't make them the same thing. When you're not using any science to inform your experiments, you're just being a disciplined artist and craftsman, and that's ok.
The author sorely missed an opportunity to collaborate with a real color chemist (they exist!) to create a truly beautiful AND comprehensive book. It definitely involves the spirit of adventure and discovery for the foraging parts, but as it is it's very rudimentary and uninformative if you're serious about actually using the inks you make.
