Description

The Glass Alchemy Ultramarine rod is a deep blue-green borosilicate glass, darker than Aquamarine. This transparent, copper-free color offers excellent thermal stability and no risk of reduction. It maintains its purity and brilliance, even during long flame-working sessions.

Ultramarine was designed for glass artists seeking a rich, easy-to-control, visually striking blue-green. The color works consistently, with no surprises. It melts evenly, retains its shine, and suits all techniques: blowing, sculpting, tubing, or stringer work.

Its dense transparency allows elegant layering. When paired with opaque colors, it creates strong contrasts; combined with lighter hues, it reveals subtle light effects. The color stays stable even during extended work times. It does not whiten or devitrify.

Ultramarine fits perfectly in the palette of artists wanting an intense, structured, and reliable blue-green. It supports various techniques and adapts to all skill levels. Its fluid texture, heat resistance, and chemical inertness make it a safe choice to enhance complex or refined pieces.

Use a neutral flame to preserve color intensity. Thanks to its predictable behavior, Ultramarine integrates easily into multicolor compositions and expresses the depth and energy of water or sky.

Like Atlantis, Ultramarine highlights light. In thin layers, it stays bright and crystalline. In thicker layers, it reveals intense aquatic depth. It subtly catches reflections, making it ideal for both complex works and minimalist creations.
