"Probably the most prolific alchemists in the [Ruthven] family were ... William and Patrick. William was reputed to have the alchemists’ Holy Grail, the ‘Philosophers Stone’. Patrick Ruthven’s alchemical notebook, known as his commonplace book, is preserved at the University of Edinburgh, and contains much correspondence, diagrams, tables, symbols, and information on various alchemical processes; which clearly highlight his knowledge of the art; both in a practical, but perhaps more importantly for this discussion, a spiritual sense. As will be demonstrated, their brother John, the third Earl of Gowrie, also had an extremely keen interest in occult subjects, and it is proposed that this interest, may have been at least one of the reasons behind the incident which took place in Perth, and which has aptly been described ever since, as the ‘Gowrie House Mystery’. Mysterious indeed, by dint of the fact no one has ever satisfactorily resolved it."

"As a historian and philosopher of chemistry, I have been intrigued by the significance of the heroic figure of Lavoisier as the founder of modern chemistry and the correlative view of chemistry as languishing in the obscure alchemical tradition that preceded his chemical revolution."

"There are even treatises by authorities, whom at least I shall not name, where they describe the ways in which they dye rock-crystals the color of emerald or other transparent stones, or make sardonyx from sard, and similarly various gems from others. Indeed, there is no fraud in life that is more profitable."

While no such treatise is preserved, traces of such texts are discernible in the so-called Stockholm papyrus, which gave numerous recipes to make imitation gemstones. The papyrus is usually classified as alchemical in nature, highlighting the links between medicine, gem making, and alchemy.

"This paper historicizes a constellation of interrelated ideas regarding the chymical principles as they developed and became resilient fixtures within a major chymical tradition. Focusing primarily on German chymists, several of whom have eluded sustained historical interest, it explores how experimental analysis was generally thought to produce sensible chymical principles, often conceived as principiata: bodies produced by combining or mixing fundamental elements or principles."
