750.pst – a pastel glass, neutral-yellow tonality. Sold at $30/pound.
Working notes: Avoid overheating to prevent “fizz”. Opacity can increase with extended annealing, with color outcomes ranging from slightly translucent cream to a warm almost-White.
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.
