Since 1972, HARIO manufactures heatproof glass in a factory without chimneys. Removing chimneys was achieved by the independent development of technology to melt raw materials of glass with electricity rather than with fuel oil. This achievement changed the concept of glass factories which were known for smoke and dust pollution to factories that provide safety for the surrounding environment as well as for the employees working inside.
