Project Gutenberg 2007-09-27 Public domain in the USA. 293 Threlfall, Richard On Laboratory Arts Produced by Jon Richfield "On Laboratory Arts" by Richard Threlfall is a scientific publication written in the late 19th century. The book serves as a practical guide for young physicists and inventors, focusing on the essential mechanical skills required for laboratory work, particularly in manipulating glass and glass-blowing techniques. Threlfall aims to provide readers with tangible methods and advice for constructing laboratory apparatus, emphasizing the importance of hands-on experience in mastering these arts. At the start of the work, the author sets the tone with a preface that highlights the necessity of mechanical skills in scientific experimentation, reflecting on the common disconnect between theoretical knowledge and practical application. Threlfall candidly acknowledges his imperfections in conveying complete methods, intent on sharing insights gained through personal experience in glass manipulation. He introduces various types of glass relevant for laboratory use, illustrating the critical nature of selecting appropriate materials, and outlines initial tips for glass-blowing, emphasizing the importance of manual dexterity over theoretical learning. Through this, readers can anticipate a detailed exploration into the artistry of laboratory crafts, making it an invaluable resource for practical learning.
