The quality standard of HARIO glass [HARIO-32] is as international standard glass as DURAN glass of SCHOTT company in Germany and PYREX7740 glass of CORNTING company in the United States, especially for the heat resistance of glass.

In general, the heat-resistant temperature of hard glass is less than 200C, but the [HARIO-32] of HARIO can withstand a temperature difference of 250C, which means that it corresponds to a sudden change in temperature. Because of the excellence of HARIO glass, Professor Xiao Chai of the University of Tokyo in Japan has carried out long-term scientific research using HARIO's high-quality glass and won the Nobel Prize in physics.

The glass of [HARIO-32] does not contain heavy metals such as lead, zinc and cadmium, so it can be used safely and safely for a long time.
