Let’s see, 5 gallons of Mazzola corn oil sells for $99.80 (including shipping) on Amazon, and 5 gallons of GLOC Quench A costs $67.81 from USA Knife Maker Supply (shipping unknown). Assuming the shipping costs are similar, the two oils cost about the same. One is engineered for quenching steel, and the other is intended for cooking. While I will concede that the corn oil smells better, I stand by my statements, which were in answer to a question posed by another forum member. Everyone here is free to embrace or reject my opinions, without trying to make things personal.
