Library: Two Sources of CaO
This tutorial video at digitalfire.com shows how to enter calcium carbonate into an recipe and then make sense of the LOI (Loss on Ignition) and formula weight that it calculates (this material loses 45% of its weight on firing and is a good example to understand the LOI concept). Next the chapter shows how you can compare the amount of CaO that wollastonite and a frit (Ferro Frit 3134) contribute in comparison and rationalize the advantages and disadvantages of each material as a source of CaO.
