Our house white we use for murrini.?We?ve shared it with other lampworkers who were in search of a good white.?Ours 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.?We especially like it under Rhea and our Oracle-Ruby.?Like all of our colors, every batch is tested 3 times for compatibility.?? The Oracle project gives 104 flame workers the option to use responsibly manufactured, low toxicity glasses in their work.?All of our Oracle glasses are made in the USA, without Antimony, Arsenic, Cadmium, Chromium, Lead, Nickel, or Selenium.
