To manufacture glass from raw materials in a laboratory, very high temperatures of up to 1700 °C are required so that the individual materials melt and combine with each other. Nabertherm has various solutions for melting small glass samples in customer’s crucibles. Small crucibles can be placed in the compact high-temperature tabletop furnace models and heated to 1700 °C. Charging the furnace is simplified considerably with a motorized lift bottom.
