SILEX
Miscellaneous
- Family: None
- Region: None
- Mined At: Unspecified
- Raw Mineral: Yes
- Generic: No
Notes
(Richard Willis)
Mineral, of the ideal form SiO2 with a typical empirical analysis of silica 100%, plus various impurities, normally considered as a variety of flint.
Hardness: 7 Density: 2.2-2.6 Water-insoluble
Refined (or not, to have its natural/impure advantages/disadvantages) from silica-rich rocks laced with several impurities. Frequently found in association with crete and other limestone deposits/zones in consequence of large scale glacial activities. Like cristobalite, it is a silica with great resistance to thermal shock, making it a silica preference for cooking ware.
