740.opl : An opal glass that strikes in the flame and kiln. With a (relatively) high resistance to thermal shock, 740.opl can be worked hot and fast in the torch flame. It is significantly stiffer than a typical opaque white glass, making it suitable for sculptural work, bead cores, and stringers.
The Oracle Project – responsibly manufactured, low toxicity glasses made in the USA, without Antimony, Arsenic, Cadmium, Chromium, Lead, Nickel, or Selenium. Balancing viscosity curves, opacity, tonality, surface tension, and thermal shock resistance, to create glass that is a pleasure to work with in the flame.
The Oracle Project Test Batches – offered direct from the glassmaker to the artisan in small batches, sold by the pound, wrapped in paper. Labeled with batch date and formula number, with a suffix to indicate glass family type example, 740.opl.
I have thoroughly enjoyed researching, developing, batching, testing, and using these colors, and it is my sincere hope that these glasses enhance your flameworking experience.
