Industry & Occupation
Classification
Summary
A manufacturing occupation that blends glass raw materials, melts them in a high-temperature furnace, and produces molten glass.
Description
Glass Raw Materials Melting Workers blend raw materials such as silica sand and soda ash, heating them to high temperatures (approx. 1,500°C) in a kiln (melting furnace) to generate molten glass. They also manage furnace temperatures, control batches, check melting status, collect samples for quality inspection, perform periodic furnace maintenance, and inspect safety devices. Much of the work involves high-temperature environments, requiring heat-resistant gear and safety and health management.
Future Outlook
While automation and labor-saving technologies are advancing, the expertise of skilled workers is essential for high-quality glass production, so a certain level of demand is expected to continue. Knowledge of environmental regulations and recycling technologies will also grow in importance.
