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.

One of the best dog toys I’ve bought off Amazon in a long time
Color: Green
My dog Rosie is a heavy tower so it is difficult to find balls she doesn’t destroy quickly. I came across this item on Amazon and it is honestly one of the best pet toys I’ve ever bought on Amazon. After a long day of work sometimes I come home and Rosie has a lot of energy. I turn this ball on fast mode and she has so much fun. I do worry about how much shaking in her mouth. I don’t wanna give her a headache, lol but there’s also a slow mode that you can press for the ball to slowly move around, but it’s a really good toy and I’m happy. I purchased it if you have a heavy tower, I wouldn’t worry about them breaking it because we’ve had it for a couple weeks now and she’s doing great.

Not indestructible, but dogs love it
Color: Green
My dog LOVES this toy. Unfortunately, she loves it so much she destroys it. I have now purchased FOUR of these, but if left unattended for 5 minutes, my American terrier breaks this apart. She loves it so much though, I keep buying replacements. This is a wonderful enrichment toy, but you must keep an eye on your toothy friend.

Engaging and Fun, But Lacks Durability for Strong-Gripped Dogs
Color: Green
The internal mechanism of this toy works very well, and the ball’s movement immediately caught the attention of my Boxer pup. He was absolutely fascinated and spent hours each day playing with it. However, while the toy’s design is engaging, the durability of the exterior leaves much to be desired—especially for dogs who tend to pick things up with a firm grip. We didn’t know what to expect since our pup hadn’t previously played with an interactive ball, so we supervised playtime and made sure to store the ball in a safe spot when we couldn’t keep an eye on him. Despite this, the ball didn’t hold up. Our pup wasn’t intentionally chewing it. He simply carried the ball in his mouth when we moved downstairs or to another room, yet the grip while he carried the ball caused significant damage to the exterior. Within about a week of regular use (approximately 40 hours in total), the ball’s outer layer became deeply gouged by his teeth. To clarify, my pup wasn’t biting down hard or trying to destroy it, but his natural grip while carrying the ball left deep grooves in the surface. In just days, these gouges made the exterior sharp to the touch and compromised the structure. By the end of the week, we couldn’t screw the cover back together after removing it to recharge the ball, which made it unusable. And I was dismayed that there aren’t replacements readily available. Overall, my pup absolutely loved this toy — it was engaging and kept him entertained for hours. However, if your dog has a strong grip or frequently carries toys in their mouth, this may not hold up as well as expected. It’s a great concept but needs a more durable outer layer and replacement hard covers to make it a long-term investment.

My dog loves this ball
Color: Green
The battery on this lasts forever. The random on/off motion and when it gets touched inducing motion just keeps my dog guessing and occupied for a long time. My dog's tail is wagging the whole time.

Great ball
I have bought two of these in different colors. My Yorkie loves them. They’re very interactive even if you don’t put the cover on it they move and if he’s not playing with it, it tends to go into sleep mode.My Yorkie got the cover off the ball within the first two minutes. But he loves the ball. Now bought 2nd ball. The ones with covers don’t work he rips the covers off.
