- Executive summary:
Results for Indigo:
Flash point > 250°C
Ignition point > 600°C
Flammability: with heating rod (800°C)
DTA: Onset temperature: 295°C
Maximum reaction: 330°C
Released heat: 100 J/g
Based on structural increments and the above data, indigo and likely vat indigo sodium salt is not explosive.
