Turboco

Highly saturated cobalt blue that reads as black when used thick and true cobalt blue when used thin; work in an oxidizing flame to avoid gray streaks.

Outcomes

• Deep black when used thick flame: OxidizingBlueBlack
  Use TurboCo thick for a near-black appearance. Keep an oxidizing atmosphere to prevent gray streaks.
• Rich saturated cobalt blue when used thin flame: OxidizingBlueIndigo
  Use TurboCo thin to reveal its highly saturated cobalt blue color. Oxidizing flame required.
• Gray streaks (undesirable) flame: ReducingGray
  Reducing the glass causes gray streaks — keep the flame oxidizing to avoid this.
