A Handbook of Laboratory Glass-Blowing

Bernard D. Bolas's A Handbook of Laboratory Glass-Blowing stands as an essential technical guide for anyone working with specialized laboratory equipment and glassware. Originally published in 1921, this comprehensive manual provides detailed instruction in the practical art of glass-blowing, a critical skill for scientists, chemists, and laboratory technicians. Through clear explanations and numerous diagrams, Bolas guides readers from fundamental principles through advanced techniques. The handbook covers cutting and sealing tubes, creating thermometer bulbs, constructing pipettes, joining dissimilar glass types, and fabricating specialized apparatus like condensers, vacuum tubes, and electrode work. Beyond basic glasswork, it explores the composition and characteristics of glass itself, annealing processes, drilling, grinding, stopcocks, calibration methods, and even improvised setups using alternative fuels. What makes this technical guide remarkable is its practical accessibility. Rather than focusing solely on commercial manufacturing, Bolas emphasizes hands-on techniques that laboratory workers can apply directly to their own needs. The content bridges theoretical knowledge about glass properties with real-world application, ensuring readers understand not just how to perform each technique, but why it works. This audiobook is ideal for chemistry students, laboratory professionals, craftspeople, and anyone interested in the practical sciences and historical technical instruction. Whether you're seeking to develop glassworking skills or understand the foundational methods of laboratory equipment construction, Bolas's expertise remains invaluable.
