| Cancrinite Treatments |
|---|
| Colorless material that has been reported to acquire blue veins on being irradiated with X-rays (Pough and Rogers, 1947). One assumes that this is the fibrous variety described by Webster . One would expect this change to be reversed by heat, and fading in light is also a possibility – Nassau (1984) |
