Cracking the Philosophers' Stone is a combination of historical commentary with reproducible chemistry that thoroughly analyses one of the most respected and mysterious chemical reactions in the history of science and technology. This book guides the reader through the origins and evolution of the archetypal recipe for the Philosophers' Stone of early Alexandrian alchemy. LaPort and Gabrielsson also provide details for various chemical reproductions based on the authors' interpretation and hypotheses of ancient chemistry preserved in encrypted form in alchemical texts. The book is written for both the curious layperson, historian of science and technology or as a source book for the experimental aspiring alchemist / chemist. This book will appeal to the student of ancient history, occult studies, historical chemistry, or the layperson familiar with the Philosophers' Stone but wants to learn more. The book is a must-have for every Rosicrucian and Freemasonic library (or the like) due to its discussion of ancient systems of thought and corresponding symbolism. Because of the human stories and historical backdrop, every layperson will find something of value to expand their understanding of the ancient world. Even scientists and specifically chemists will be fascinated with the reproducible chemical experiments presented in this ground-breaking work. The book is actually three books in one: 1) an introduction to alchemy, 2) a detailed history of alchemy's origins and evolution, and 3) a technical reference for actual reproducibility of alchemy's most sought-after prize - the Philosophers' Stone. Cracking the Philosophers' Stone is organized into three major sections. The first provides the reader with an overview of the Philosophers' Stone in the context of a general early history of alchemy. This foundational understanding serves as a framework for introducing newcomers and general enthusiasts to alchemical history, substances and processes discussed further into the work. In this section, the reader is systematically guided through major historical bifurcations that allowed for the evolution of technique and novel recipes for the Philosophers' Stone. This section is written in such a way that the reader follows the authors' sense of discovery and logic in a pedagogical fashion. Section two is a record of reproducibility. It includes details of each process, complete with frank discussions in the language of chemistry, which greatly facilitate review and reproduction of the experiments and syntheses detailed in the book. It is the 'how-to' section, if you will. Section three explores the practical applications for the Philosophers' Stone along with a hypothesized mechanism of action for each application. Conclusions are contextually counter-balanced by traditional alchemical texts and original interpretations.

Great Pillow and Highly Adjustable
Team Name: Eden, Size: King, Color: Classic
I have used a Claritin Down Alternative Pillow in the past, but they are no longer available. I am very picky with my pillows and have had a difficult time finding one that fits my needs. I decided to purchase the Coop Pillow despite the high cost. After several weeks of use, I am glad I found this one. The pillow has just the right amount fluff and support. I like that it comes with extra fill that I can use to adjust the its firmness, but I didn't need it. I'm a side sleeper and it was great right out of the box. The outer shell of the pillow is soft and very good quality. I am so glad that I found an alternative to my Claritin Pillow. The reason I only gave it 4 stars are for two simple reasons. First, the cost. This product is very comfortable, but there is no magic to its construction. The fill appears to be just finely shredded memory foam. The extra fill doesn't even come in a storage bag. It is wrapped in plastic. If you open it, you will need to find a separate storage container to put the excess fill. For this price, I would expect more. Second, this pillow is advertised as being "cool" to sleep on. However, I find it warmer than other pillows to the point it seems to trap heat. My wife has the standard Coop Pillow and I feel that it is "cooler" than this version. Of course, this is very subjective and you will need to test for yourself. Overall, this is a great pillow that has endless adjustability due to the extra fill provided. A pillow for everyone!

Quality & Comfort with Fully Adjustable Support
Team Name: Eden, Size: Queen, Color: Classic
I used to buy pricey, handmade, 100% down pillows—until I learned about the cruelty behind down production. I stopped using down entirely: pillows, comforters, jackets, everything. Then began the long search for something that could at least come close to the comfort of down, I tried Tempur and countless others, but nothing came close. As a side sleeper, I need a pillow that’s high, SOFT, supportive, conforming, and huggable. After wasting money on at least five different pillows, I finally tried the Coop Home Goods Eden Pillow because of its adjustability. The cover is kind of thick, soft, and well‑made (I use a nice cotton pillow cover over it). The filling is soft and high quality. You can customize the height and firmness however you like. It even comes with plenty of extra fill. To my surprise, the shredded foam doesn’t make the pillow clumpy—something every other similar pillow I tried struggled with. The surface stays smooth and soft, and it’s been a total game‑changer. It’s a keeper! I’ve had mine for almost four years now and only needed to add more filling once, about 8–10 months ago. Toss it in the dryer on low with a couple of tennis balls, and it fluffs up like new. And the icing on the cake: outstanding customer service. I highly recommend this pillow and will definitely buy it again

Nothing like the original Eden, don’t buy the name
Team Name: Eden Cool+, Size: King, Color: Classic
I’ve had the original Coop Eden for 5+ years and it has been a great pillow, very comfortable, soft but supportive but when I purchased a new mattress I wanted to refresh my pillow and saw the Eden Cool+ and wanted to give it a try. I figured it could only be better than the original Eden…but it is not. While the outer cover is noticeably cooler to the touch, it is not soft like the Eden. Also, this cool material mostly gets negated if you use a pillow case anyway. The shaped fill material I would also say is “lumpier” for lack of a better word than the shredded material in the original. The combination of the harder, less supple outer casing and the lumpy material just aren’t a good combination. I will say it does sleep slightly cooler than the original Eden but not enough for the sacrifice in comfort. I would absolutely consider going back to the original Eden.

Unmatched Pillow with Unmatched Customer Service!!! 5 STAR ALL AROUND
Team Name: Eden Cool+, Size: King, Color: Classic
## A Dream Come True (and Customer Service to Match!) From the moment I first laid my head on the Coop Eden Cool+ pillow, I knew I'd found something special. It's truly a game-changer for hot sleepers like me. The "Cool+" technology isn't just a gimmick; it actually works to keep my head and neck comfortably cool throughout the night, leading to the most refreshing sleep I've had in years. The adjustable fill is brilliant, allowing me to customize the loft perfectly for my sleep style, which means no more waking up with neck pain. The support is fantastic – it cradles my head without feeling too firm, and it holds its shape beautifully. However, what truly elevates my experience to a full five stars, beyond the exceptional product itself, is the **dedicated and outstanding customer service**. I had a minor issue with my initial pillow (a rare manufacturing defect, which can happen with any product). I reached out to Coop Home Goods, and their response was nothing short of phenomenal. They were incredibly prompt, empathetic, and went above and beyond to resolve the issue swiftly and completely. They genuinely cared about my satisfaction and ensured I was left with a perfect product. It's rare to find a company that not only produces a superior product but also stands behind it with such integrity and genuine concern for their customers. The Coop Eden Cool+ pillow is an investment in your sleep, and knowing that you're backed by such an incredible customer service team makes it an even easier decision. Highly, highly recommend!
