Industry & Occupation
Classification
Summary
A technical job that consistently handles everything from raw material blending to melting, purification, forming, and inspection of specialty glass, manufacturing high-performance glass products for optical, electronic, heat-resistant, and other applications.
Description
Specialty glass workers are specialists who blend raw materials such as silica, borosilicate, and fluorides, and manufacture glass in high-temperature melting furnaces. They design compositions and optimize melting conditions suited to product applications, perform purification operations, form using blow glass, drawing forming, center rod method, etc., then complete the product through annealing, surface treatment, and dimensional/defect inspection. They engage in mass production and prototyping of high-performance glass used in diverse fields such as optical lenses, glass substrates for electronic components, heat-resistant glass, and optical fibers. Maintenance of manufacturing equipment and safety/health management are also important tasks.
Future Outlook
Demand for high-performance glass is increasing with the development of 5G/6G communications and semiconductor/display industries. Skills in automation/digital control technology introduction and low-environmental-impact material development will enhance market value.
