Aimed at laboratory technicians and budding glassblowers, "A Handbook of Laboratory Glass-Blowing" by Bernard D. Bolas offers a practical guide to working with glass for scientific purposes.
Here's a breakdown of the book's key content:
Getting Started:
- Introduction to the art of glassblowing, emphasizing essential principles and safety precautions.
- Choosing the right tools, equipment, and types of glass for the job.
Fundamental Techniques:
- Straightforward procedures for common laboratory glassware manipulations, including:
- Cutting and sealing glass tubes.
- Crafting specific elements like thermometer bulbs, pipettes, and absorption bulbs.
- Joining tubes and building branches onto existing glassware.
- Blowing bulbs and shaping basic apparatus.
- Using glass rods and strips for shaping and support.
- Cracking and directing glass breaks for controlled shaping.
- Gripping glassware for manipulation, especially when using corrosive solutions.
Advanced Techniques:
- Creating internal seals, air traps, spray arresters, and filter pumps within glassware.
- Constructing various condensers (plain, double surface, and spherical).
- Building Soxhlet extraction tubes for fat analysis.
- Working with glass for vacuum tubes and electrode work.
- Encasing thermometers and crafting alarm or recording thermometers.
- Techniques for spinning molten glass for specific formations.
Beyond the Basics:
- Understanding the composition and properties of different types of glass.
- Annealing (stress relieving) glassware for stability and durability.
- Non-fusion methods for shaping and modifying glass, including drilling and grinding.
- Attaching stopcocks to glassware for flow control.
- Marking and calibrating laboratory apparatus, including thermometers.
- Techniques for safely evacuating air from glassware.
- Joining glass to metal for specialized equipment.
- Silvering glass for reflective surfaces.
Making Do with Less:
- Improvising glassblowing setups using alternative fuels like oil.
- Utilizing scrap glass to create small rods and tubes.
- Analyzing commercially manufactured glassware to understand construction techniques.
- Concluding remarks on the essential elements for successful glassblowing practice.
The book focuses on clear instructions and practical examples, making it a valuable resource for those interested in learning the art of laboratory glassblowing.
