Key Responsibilities and Required Skills for Glass Maker

🎯 Role Definition

The Glass Maker is a skilled tradesperson responsible for producing high-quality glass products through hot-work (blowing, casting, furnace work) and cold-work (cutting, grinding, polishing), operating industrial furnaces and kilns, interpreting technical drawings and patterns, and maintaining strict safety and quality standards. This role blends hands-on craftsmanship with process control, material science awareness, and collaboration with design and production teams to deliver both artistic and production-run glass items — from blown art pieces and scientific glassware to architectural components and commercial containers.

Core Responsibilities

Primary Functions

Operate and monitor high-temperature furnaces, glory holes and annealing kilns, precisely regulating temperature, burner settings, and feed rates to maintain glass melt quality and consistent working conditions for continuous production.
Gather, weigh, and prepare raw materials and batch mixes (silica, soda ash, lime, cullet, and colorants), accurately following batch sheets and formulations to meet chemical and optical specifications.
Execute skilled hot glass techniques including gathering, marvering, blowing, shaping, and finishing glass using blowpipes, pontils, jacks, paddles and other hand tools to create both one-off art pieces and repeatable production items.
Set up, maintain and operate molds and casting forms for pressed, blown-in-mold, and cast glass production, ensuring proper alignment, release agent application and cycle timing for consistent output.
Carry out cold-working operations such as cutting, grinding, drilling, sandblasting, and polishing to finish edges, create facets, and achieve specified surface textures and tolerances for end-use parts.
Perform annealing schedules and load/unload kilns according to product geometry and internal stress considerations, document kiln cycles, and verify part temperatures with pyrometers and temperature probes.
Inspect incoming materials for conformity (cullet size, moisture, contamination, color consistency) and maintain accurate inventory records; escalate variances to procurement or quality teams.
Read and interpret technical drawings, product specifications, CAD files and prototypes to reproduce dimensions, tolerances and aesthetic details for custom and production pieces.
Conduct in-process and final quality control checks — measuring wall thickness, diameters, optical clarity, stress testing and defect grading — and execute corrective actions such as rework, trimming or scrap decisions.
Calibrate and maintain hand and power tools (jacks, shears, grinders, lathes), burners, torches and temperature control systems, and perform or coordinate scheduled preventive maintenance to minimize downtime.
Apply colorants, powdered frits, metallic foils and surface treatments precisely to achieve specified hues and effects while documenting recipes for reproducibility across batches.
Follow and enforce strict safety protocols including heat safety, chemical handling, eye and respiratory protection, hot glass handling, confined space and lockout/tagout procedures to maintain a zero-injury work environment.
Troubleshoot production issues such as glass viscosity variations, furnace bloom, bubble entrapment, mold release problems and tooling wear, using process data and hands-on adjustments to restore consistent yields.
Collaborate with designers, engineers and quality teams to prototype new products, iterate on tooling and production methods, and scale small-batch techniques into reliable production processes.
Package and prepare finished glass products for shipping, selecting appropriate protective materials, documenting lot and inspection codes, and coordinating logistics for fragile items to prevent transit damage.
Train and mentor junior glassmakers, apprentices and temporary staff in safe hot shop practices, tool use, quality standards and production techniques to build team capability.
Maintain accurate production logs, kiln records, defect reports and batch documentation to support traceability, continuous improvement and regulatory compliance.
Manage energy and melt efficiency by adjusting furnace operation, recycling cullet effectively and following lean manufacturing initiatives aimed at reducing waste and lowering per-unit energy costs.
Implement and document process improvements to increase throughput, reduce rejects and shorten cycle times, using root-cause analysis and data-driven problem solving to deliver measurable gains.
Ensure environmental, health and safety compliance — including hazardous waste handling, emissions control, and workplace ventilation — and support regulatory inspections and audits.
Fabricate and repair tooling, jigs and fixtures as needed, and work with external vendors to source specialized molds or replacement components when in-house fabrication is insufficient.
Support custom orders and one-off commissions by coordinating design reviews, estimating production time and materials, and providing technical input on manufacturability and lead times.
Prepare and present samples and production capability demonstrations for sales, product development and client review sessions, clearly communicating limitations, costs and recommended alternatives.

Secondary Functions

Participate in cross-functional production planning meetings to align lead times, capacity and raw material availability with sales and customer requirements.
Support continuous improvement initiatives such as 5S, Kaizen events and waste-reduction projects that target quality, throughput and safety.
Assist with purchasing cycles by providing technical specifications and quantity forecasts for raw materials, colorants and consumables.
Document best practices, standard operating procedures (SOPs) and onboarding materials for use by the team and apprentices.
Provide after-sales technical support to customers for product care, annealing considerations and installation guidance when required.
Contribute to studio or factory maintenance schedules, including cleaning of ducts, workstations and cooling systems to preserve equipment life and product quality.
Help coordinate and execute workshops, demonstrations or studio tours that support marketing and customer engagement activities.
Maintain sample libraries, color logs and recipe archives to support rapid quoting and consistent color matching for repeat clients.
