It is a type of glass that was originally produced as a byproduct of metal smelting, specifically from the \u003cstrong\u003eslag\u003c\/strong\u003e (the waste material) left behind in the refining of metals like copper, iron, or lead. Over time, slag glass became a valuable material in its own right, prized for its unique, colorful appearance and use in various forms of decorative art and jewelry. Before globalization, back when it was very difficult to order gem rough from foreign countries, slag glass was a popular material for USA based gem cutters to work with when they did not have natural gem rough on hand.\u003c\/p\u003e\n\u003cp\u003eSlag glass is often vibrant, with swirling patterns or a \u003cstrong\u003emarbled effect\u003c\/strong\u003e that can feature every shade of the rainbow. The presence of various minerals in the slag determines the color and patterning, which can include multi-colored veins or opaque spots. It can range from opaque to semi-translucent, and sometimes even transparent, depending on the specific composition of the slag.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\" class=\"p1\"\u003e\u003cb data-mce-fragment=\"1\"\u003eChemical Composition\u003c\/b\u003e\u003cspan data-mce-fragment=\"1\"\u003e: SiO2\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cspan data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eGrade\u003c\/strong\u003e: Lapidary Grade\u003cbr\u003e\u003c\/span\u003e\u003cspan data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eAppearance\u003c\/strong\u003e: Transparent\/ Translucent\u003cbr\u003e\u003c\/span\u003e\u003cstrong data-mce-fragment=\"1\"\u003eInclusions\u003c\/strong\u003e: None\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cb data-mce-fragment=\"1\"\u003eApproximate Size of\u003c\/b\u003e\u003cb data-mce-fragment=\"1\"\u003e 1 pc\u003c\/b\u003e\u003cspan data-mce-fragment=\"1\"\u003e: 9cm x 6cm x 0.5cm\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/span\u003e\u003cstrong data-mce-fragment=\"1\"\u003eApproximate Weight of 1 pc\u003c\/strong\u003e\u003cspan data-mce-fragment=\"1\"\u003e: 70g\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\" class=\"p1\"\u003e\u003ci data-mce-fragment=\"1\"\u003e\u003cspan data-mce-fragment=\"1\"\u003eRough is rough.
