Whether melting for the die casting of brass is done under either oxidizing or reducing conditions, it is advisable to maintain the absorption of gas at a minimum since the absorbed gas has to be removed before pouring. When the melting process is performed in a neutral environment, a protective cover (typically, charcoal) has to be employed to prevent oxygen and hydrogen’s further absorption. Dissolved hydrogen is eliminated from the molten metal by blowing inert gas into it. This inert gas is typically nitrogen. The dissolved hydrogen in the melt is diffused into inert gas and leaves it with the bubbles. This process is called “degassing”.
