Core Responsibilities

Primary Functions

Interpret complex blueprints, technical drawings, and specifications to fabricate intricate scientific glassware such as distillation apparatus, vacuum manifolds, and reaction vessels.
Operate glassblowing lathes, bench torches, and specialized hand tools to heat, bend, shape, and fuse glass tubing and rods to precise dimensions and tolerances.
Execute both free-form and mold-blowing techniques to create custom artistic pieces, ensuring the final product aligns with the intended aesthetic vision and maintains structural integrity.
Manage the complete annealing process by carefully programming and monitoring kilns to slowly cool finished glassware, effectively relieving internal stresses to prevent future cracking or failure.
Perform complex glass-to-glass and glass-to-metal sealing operations, creating vacuum-tight seals essential for scientific and industrial applications.
Conduct in-process quality control checks, visually inspecting work for flaws, bubbles, stress fractures, or dimensional inaccuracies and making real-time adjustments.
Select appropriate types of glass, such as borosilicate, quartz, or soda-lime, based on the project's requirements for thermal shock resistance, chemical durability, and optical clarity.
Skillfully execute cold-working techniques, including cutting, grinding, lapping, and polishing, to finish and refine glass pieces after they have been formed and annealed.
Repair and modify broken or faulty scientific glassware, demonstrating advanced problem-solving skills to salvage expensive and complex apparatus.
Handle, store, and work with high-pressure gas cylinders (oxygen, propane, natural gas) and ventilation systems, adhering to all established safety protocols.
Develop and document standardized procedures for repeatable production jobs, ensuring consistency and quality across multiple units.
Collaborate directly with research scientists, engineers, or artists to understand their needs and provide expert guidance on the feasibility and design of custom glassware.
Create prototypes and proof-of-concept models for new products, iterating on the design based on performance testing and client feedback.
Manipulate molten glass gathered from a furnace on a blowpipe or punty, using tools like jacks, shears, and paddles to shape the piece while constantly rotating it.
Apply colors, patterns, and surface textures to glass during the hot-working process using frits, powders, or canes to achieve specific decorative effects.
Set up and calibrate glassworking equipment before beginning a project, ensuring torches have the correct flame chemistry and lathes are properly aligned.
Maintain a high degree of focus and concentration for extended periods while working with extreme temperatures and delicate materials.
Perform final inspection of completed products to ensure they meet all functional requirements, aesthetic standards, and client specifications.
Estimate material usage and production time for custom projects to assist in accurate quoting and project planning.
Keep a detailed log of work performed, noting any challenges encountered or modifications made to the original design for future reference and process improvement.

Secondary Functions

Perform routine preventative maintenance, cleaning, and minor repairs on glassblowing equipment, including lathes, torches, and annealing ovens, to ensure safe and efficient operation.
Maintain an accurate inventory of raw materials, including various sizes of borosilicate and quartz tubing, rods, and specialized components, and communicate procurement needs.
Contribute to the continuous improvement of studio or workshop processes by suggesting new techniques, tools, or safety enhancements.
Mentor and train junior glassblowers or apprentices, patiently demonstrating proper techniques and safety protocols to foster skill development within the team.
