| 1. | In cryptohalite, each anion is coordinated to 12 others.
|
| 2. | Bararite has about a 6 % greater density than cryptohalite.
|
| 3. | Above 13 �C ( 55 �F ), almost pure cryptohalite emerges.
|
| 4. | In Pennsylvania, bararite normally comes as tiny inclusions in cryptohalite crystals.
|
| 5. | Whereas cryptohalite belongs to the isotropic optical class, bararite is uniaxial negative.
|
| 6. | These hold primarily cryptohalite but also some bararite.
|
| 7. | Afterward, it quickly changes to cryptohalite.
|
| 8. | Still, bararite is fragile enough that grinding it for spectroscopy will produce a little cryptohalite.
|
| 9. | In Barari, silica and cryptohalite.
|
| 10. | Bararite and cryptohalite in their pure forms, for the most part, grow out of these nodules.
