Glass Blowers, Molders, Benders, and Finishers
Tasks
Core Tasks Include:
- Inspect, weigh, and measure products to verify conformance to specifications, using instruments such as micrometers, calipers, magnifiers, or rulers.
- Record manufacturing information, such as quantities, sizes, or types of goods produced.
- Heat glass to pliable stage, using gas flames or ovens and rotating glass to heat it uniformly.
Supplemental Tasks Include:
- Blow tubing into specified shapes to prevent glass from collapsing, using compressed air or own breath, or blow and rotate gathers in molds or on boards to obtain final shapes.
- Set up and adjust machine press stroke lengths and pressures and regulate oven temperatures, according to glass types to be processed.
- Shape, bend, or join sections of glass, using paddles, pressing and flattening hand tools, or cork.
- Develop sketches of glass products into blueprint specifications, applying knowledge of glass technology and glass blowing.
- Determine types and quantities of glass required to fabricate products.
- Place rubber hoses on ends of tubing and charge tubing with gas.
- Superimpose bent tubing on asbestos patterns to ensure accuracy.
- Place electrodes in tube ends and heat them with glass burners to fuse them into place.
- Strike necks of finished articles to separate articles from blowpipes.
- Spray or swab molds with oil solutions to prevent adhesion of glass.
- Cut lengths of tubing to specified sizes, using files or cutting wheels.
- Place glass into dies or molds of presses and control presses to form products, such as glassware components or optical blanks.
- Design and create glass objects, using blowpipes and artisans' hand tools and equipment.
- Repair broken scrolls by replacing them with new sections of tubing.
- Operate and maintain finishing machines to grind, drill, sand, bevel, decorate, wash, or polish glass or glass products.
- Operate electric kilns that heat and mold glass sheets to the shape and curve of metal jigs.
