Neptune is a lovely blue AuraTone™. It works smoothly in a wide range of flame types. Radiant, or “incidental” heat will grow the inner atmosphere. It is also typically more pronounced in thicker forms.
This color is slightly stiffer than clear and requires higher temperatures for proper annealing. Garage often and give the piece plenty of soak time based on its size and shape.
Recommended Garage/Anneal temp: 1085°F
