This item is approximately (92+/-) 4mm Blue Goldstone (man-made) Round Beads temporarily strung on monofilament line. Goldstone is a type of glittering glass made in a low-oxygen reducing atmosphere. The finished product can take a smooth polish and be carved into beads, figurines, or other artifacts suitable for semi-precious stone, and in fact goldstone is often mistaken for or misrepresented as a natural material. The most common form of goldstone is reddish-brown, containing tiny crystals of metallic copper that require special conditions to form properly. The initial batch is melted together from silica, copper oxide, and other metal oxides to chemically reduce the copper ions to elemental copper. The vat is then sealed off from the air and maintained within a narrow temperature range, keeping the glass hot enough to remain liquid while allowing metallic crystals to precipitate from solution without melting or oxidizing. After a suitable crystallization period, the entire batch is cooled to a single solid mass, which is then broken out of the vat for selection and shaping. The final appearance of each batch is highly variable and heterogenous. The best material is near the center or "heart" of the mass, ideally with large, bright metal crystals suspended in a semitransparent glass matrix. These beads are great for making necklaces, bracelets, earrings and more. Any questions just ask. Many More Items Coming Soon from Alice's Looking Glass Jewelry!!! Check out my other items!
