An alternative mineral in the glass and ceramic industry: Nepheline

Commercial nepheline syenite ore must have less than 2% Fe 2 O 3 content, a property that unfortunately is not very common in deposits that are close to markets. With the exception of colourless glass, nepheline syenite for glass production requires the Fe 2 O 3 content to be reduced to 0.35% through processing ( Bolger, 1995 ). In this study ...

Who Are the Nephilim?

The Nephilim were the heroes of old, men of renown. The people of the world were in a state of moral decay, and had fallen spiritually. The word nephilim is not a name title, and it should have been translated as the "fallen ones.". It is referring to those who have fallen spiritually and are in moral decline.
