Library: Feldspar Teaches Us About Formulas, LOI, Unity

The first chapter in the lessons section of the INSIGHT manual (and matching video at digitalfire.com) deals with the basics of oxides, formulas and analyses. It shows the relationship between materials and oxides and how to enter a single material into a recipe and calculate its chemistry, and understand what unity, formula weight and LOI (loss on ignition) are. It does this using a theoretical and actual feldspar (the concept of a theoretical material is demonstrated).
