    Abstract: The present disclosure relates generally to a rolled metal article. In particular, the present disclosure provides an article comprising a metal substrate and a taggant sheared into the substrate. The metal substrate has an upper surface, a lower surface, and a middle portion therebetween. The taggant is embedded within at least one of an upper portion and a lower portion. The present disclosure provides a method for making a rolled metal article having a taggant embedded therein and a method for making an embossed metal coin including a taggant embedded therein.

    Abstract: A method of purifying and casting a material comprising placing a material to be purified within a crucible, the crucible located within a purification chamber; providing thermal energy to the material to maintain the material in a molten state; providing a purification gas into the molten material to purify the material until a first measured condition is attained; passing the material in a fluid state from the purification chamber having a first atmosphere to a casting chamber having a second atmosphere, the purification chamber in fluid communication with the casting chamber such that the material passes from the purification chamber to the casting chamber without exposure to a third atmosphere; placing the material into a mold within the casting chamber; cooling the material within the mold to form a cast material.
