Methods for engineered cellular magmatic usable as filter media and articles thereof are disclosed. For example, the magmatics may include one or more infiltration materials that are configured not to sinter when a foamed mass is formed. The infiltration materials may be enclosed in cells of the foamed mass and may be floating and/or fixed to the cell walls.
