1-Atmosphere Gero Furnace with Controlled Gas Atmosphere

The 1-atmosphere Gero furnace is a high-temperature system capable of operating up to 1800°C, primarily used for preparing starting glasses for experiments and conducting partitioning experiments between melts and minerals in model systems. It features an inert and gas-tight alumina-ceramic tube, allowing for precise control over the gas atmosphere. Researchers can control oxygen fugacity or introduce specific gases such as SO2, N2, or CO2, enabling a wide range of redox conditions. Experiments can be performed in sealed inert capsules, open crucibles, or with samples suspended from wire loops. The furnace also supports Differential Thermal Analysis (DTA), which measures small differences in temperature to determine the thermal energy released or consumed during reactions, such as the enthalpy of melting or decarbonation. Experiments can be quenched by dropping them into a cold oil bath or by simply pulling them out of the furnace.
