751.pst – a pastel glass, off-white tonality.
Working notes: 751.pst is a smooth, soft glass with a “short” viscosity curve. Opacity is variable depending on thermal history of the workpiece and annealing time and temperature.
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.
