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.
• 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.
