NS-075 Indigo Aventurine is a fully opaque deep night blue aventurine color. It is well suited for stringer application and blown work. It is easily worked and can take a lot of heat. To keep the color most vibrant, work in a neutral to slightly oxidizing flame. It looks great over NS-054 Star White and be sure to try encasing it with NS-070 Ice Blue!
