In order to melt glass out of quartz sand, 1,500 °C is required even with the addition of sodium carbonate (soda). This high temperature is generated with gas. Nevertheless, many natural gas processes can already be converted to electric heat generation. For example, to efficient and sustainable hot air systems with special nozzles and heat recycling or infrared systems from Leister. But there is still one downside: Here, too, gas independence only works if the electricity to run the hot air and infrared systems comes from renewable energy sources. Despite that, the reduction of gas consumption is one of many important steps in the fight against climate change on our planet.
