Experimental Petrology and Metallurgy/Starting materials

Decarbonation

 * 1) Put powders into a crucible
 * 2) Place in 1 atm furnace at room temperature
 * 3) Heat slowly (over at least two hours to avoid spitting during decarbonation) to around 200 K above decarbonation temperature.

Gas mixing
Pelletisation

Gas mixing with H2-CO or CO-CO2. Make sure there is >20 mol% of both gases to ensure good control of fO2.
