Flint Glass Manufacturing Worker
ふりんとがらすせいぞうこう
Industry & Occupation
Classification
Summary
Flint glass manufacturing workers are specialists who produce high-refractive-index glass containing lead, handling everything consistently from raw material mixing to melting, forming, and inspection.
Description
Flint glass manufacturing workers accurately mix raw materials such as silica, lead compounds, and fluxes, and melt the glass in a melting furnace at approximately 1400°C. The molten batch is fed to forming equipment and processed into the specified shapes using methods such as blown glass, press forming, and drawing forming. It is then slowly cooled in an annealing furnace, and quality such as bubbles, impurities, and refractive index is confirmed using inspection equipment or visual inspection. Furnace temperature control, machine maintenance, and safety and health management are also important tasks.
Future Outlook
With increasing demand for glass products in optical and electronic material applications, demand for high-quality flint glass manufacturing technicians remains stable. Adaptation to energy-saving technologies and new materials is required due to environmental regulations and development of alternative materials.
