Methods for engineered polyphase cellular magmatics and articles thereof are disclosed. For example, the magmatics may include multiple phases including a crystalline phase and an amorphous phase. The magmatics may also include one or more reactive agents that may be disposed within cell structures of the magmatics and/or on an exterior of the magmatics, giving the resulting magmatics reactive properties that may differ based on the selected reactive agents and/or placement of the reactive agents within and/or through the magmatics.
