👉 The Orleans fluid, also known as the Orleans ether or the Orleans ether solution, is a historical chemical mixture that gained notoriety during the late 19th and early 20th centuries, particularly in the field of chemistry and alchemy. It was composed primarily of ether (dimethyl ether) and various other volatile substances, including alcohol and sometimes sulfuric acid. This fluid was highly flammable and had a sweet, floral scent, which led to its association with the occult and spiritualist practices. The Orleans fluid was used in experiments to explore chemical reactions, particularly in the field of organic chemistry, and was believed by some to facilitate communication with spirits or to enhance the effects of rituals. However, its use was largely discredited due to safety concerns and the discovery that ether could be toxic or explosive.
