Cordierite Iolite Vs Snowflake Obsidian Fracture
Fracture is an important parameter when you compare Cordierite Iolite and Snowflake Obsidian Physical Properties. It is necessary to understand the significance of these properties, before you compare Cordierite Iolite Vs Snowflake Obsidian fracture. Whenever a gemstone chip breaks, it leaves a characteristic line along its breakage. Such lines are known as fracture and are used to identify the gemstones in their initial stages of production when they are in the form of rough minerals. Fracture is usually described with the terms “fibrous” and “splintery” to denote a fracture that usually leaves elongated and sharp edges. Fracture observed in Cordierite Iolite is ConchoidalWalter Schumann, Gemstones of the world (2001), Uneven and Uneven. Snowflake Obsidian fracture is ConchoidalArthur Thomas, ConchoidalArthur Thomas, Gemstones (2009) and Gemstones (2009).
