Interesting work on an energy-saving stove by Friedrich Christoph Müller (1751-1808), a widely interested pastor in Schwelm, Westphalia, who wrote several works on astronomy and trigonometry. In 1799 he published a short article about an energy-saving stove in use in the county of Mark, on which he expanded in the present book. The stove had a special iron box for fuel which prevented loss of heat. The coal mines of Westphalia stimulated the use of coal and in the present work Müller also discusses ways of baking bread, brewing beer and distilling gin by using coal instead of wood. The different stoves are depicted on seven copper engravings at the end of the book.
