Soda-lime glassrod produced by Double Helix, Oracle White has a nice viscosity curve, it allows for some light transmission which creates a brighter appearance. It’s good as a base white, in thick stringer and in latticino.

The Oracle project is an extension of what we’ve already done with Aether, Zephyr and Rhea; create low-toxicity, essential glass colors for the flame. We will be producing colors free from antimony, arsenic, cadmium, chromium, lead and selenium. Oracle-Black, Oracle-White (coming in 2018), Rhea, and Zephyr give 104 flame workers the option to use responsibly manufactured, low toxicity glasses in their work.

Double Helix glass is compatible with all Effetre, Vetrofond and Precision 104 colours.
Glass for flamework: beads and spun glass.
