Core Responsibilities

Primary Functions

Interpret and work from complex blueprints, engineering drawings, CAD models, and verbal instructions to fabricate custom glass components.
Set up, operate, and maintain a variety of glassworking equipment, including hand torches, bench burners, glass lathes, and annealing ovens.
Skillfully heat, bend, stretch, and shape borosilicate, quartz, and other types of glass tubing and rods to precise angles, curves, and dimensions.
Perform advanced glass-to-glass and glass-to-metal sealing techniques to create vacuum-tight, durable joints for scientific and industrial apparatus.
Fabricate complex glass components such as manifolds, distillation apparatus, reaction vessels, stopcocks, and vacuum systems.
Conduct in-process and final quality control inspections to ensure products are free from stress, cracks, bubbles, and other defects.
Use precision measuring instruments like calipers, micrometers, and protractors to verify parts meet strict dimensional tolerances.
Operate annealing ovens to properly heat-treat finished glass pieces, removing internal stress and ensuring structural integrity.
Grind, fire-polish, and finish glass components to achieve specified surface quality and smooth edges.
Troubleshoot and resolve fabrication challenges, adjusting techniques and temperatures to accommodate variations in glass and environmental conditions.
Work with various gas mixtures (oxygen, natural gas, hydrogen) and safely manage their use according to safety protocols.
Perform leak testing on finished apparatus, often using tools like a Tesla coil or a Helium Mass Spectrometer Leak Detector.
Construct and repair intricate scientific glassware, requiring a high degree of patience and problem-solving.
Select appropriate glass types and sizes from inventory based on project specifications for thermal, optical, or chemical properties.
Execute fine, detailed work requiring exceptional dexterity, such as creating internal seals, capillaries, and multi-jacketed vessels.
Document production processes, record measurements, and maintain logs for quality assurance and traceability.
Manage workflow to meet production schedules and deadlines without compromising quality or safety.
Create prototypes and work collaboratively with engineers or designers to refine and improve new product designs.
Clean and prepare glass materials prior to fabrication to ensure purity and prevent contamination in the final product.
Adhere to all company and industry safety standards, including the proper use of personal protective equipment (PPE) like didymium glasses.

Secondary Functions

Maintain a clean, organized, and safe work environment within the glass shop.
Perform routine preventative maintenance, calibration, and minor repairs on glassworking tools and equipment.
Assist in managing inventory of raw materials, including glass tubing, rods, and compressed gases.
Contribute to continuous improvement initiatives by suggesting process enhancements for efficiency and quality.
