Glycerin
Crude glycerin can come from many sources, including fat splitting, saponification and transesterification.Crown designs each glycerin plant to make a high-quality product from any of these feedstocks by first removing the majority of the MONG (Matter Organic Non-Glycerin) and enough water to concentrate the glycerin to at least 80% purity.

How is Iron Refined from Ore? (with pictures)
To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process. To coax the oxygen atoms away from the ore requires heat and an alternate atomic partner for the oxygen to bond to.

How Iron Was Made
Iron making evolved over a few thousand years. Using the ancient "bloomery" method, iron ore was converted directly into wrought iron by heating the ore while at the same time melting the ore's impurities and squeezing them out with hand hammers. This is also called the "direct process."

The procedure is accomplished in three ways: refining by fire, by electrolytic, or by chemical methods. Iron, copper, and lead are fire-refined by selective oxidation. In this process, oxygen or air is added to the impure liquid metal; the impurities oxidize before the metal and are removed as an oxide slag or a volatile oxide gas.
