The Glass Alchemy Eclipse rod is one of the most popular and easy-to-use blacks in the glassworking world. It stands out for its deep smoky black color, which retains its dark hue even when pulled into thin layers. One of its main features is its durability. Often described as “bulletproof,” Eclipse contains no chrome, significantly reducing the risk of graying or cracking, common issues with other blacks. For those seeking a more saturated black, Raven may be a better option.

When working with Eclipse, it is versatile enough to adapt to different flame atmospheres. However, as with most glassworking projects, it is best to use a neutral flame for optimal results. Eclipse can withstand long working hours and a variety of flame conditions, making it a reliable choice for those who work with glass for extended periods.

One of the major advantages of Eclipse is its ability to endure multiple heatings without losing its integrity. Whether subjected to several kiln cycles or prolonged flame exposure, Eclipse retains its color and smooth texture. Mike Shelbo has successfully used it in large marbles and finds that Eclipse outperforms other blacks, offering a deep, glossy finish even after extended exposure to the flame. The Glass Alchemy Eclipse rod has become his go-to black, providing unparalleled durability and workability compared to other colors in his palette.
