Oracle-Black Seconds (1/2lb)

Oracle-Black made in typical Double Helix fashion; with unconventional approaches to glass chemistry using low toxicity ingredients. Oracle-Black has smooth working characteristics, reads “darker” than some existing black glasses, does not spread excessively, and can be worked very hot without boiling. It is made in USA without Antimony, Arsenic, Cadmium, Chromium, Lead, Nickel, or Selenium.  Rods are dark blue but strike to black during the annealing cycle.  Stays neutral with striking colors but reacts to luster colors.

For maximum opacity, particularly in thin applications, briefly cool the bead then lightly flame strike (30 seconds) before annealing for 2 hours or more at 950F.

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.

What are seconds?
Our second quality rods are less than perfect in shape. They may be too large, too small, too short, chipped, twisted or have an inclusion. They have all passed both our compatibility test and our color test, just not our pretty rod test.
