I have often posted in fluxing threads regarding saw dust and other carbohydrate fluxing agents that grain products like grits, corn meal, cream of wheat etc could be used to flux. My personal choice is chicken scratch feed. It is just a mixture of grains. I was smelting this weekend the pot got a little hot 800°. I threw in some chicken feed. It smoked and then the corn began to pop. The tinsel fairy did not come but I am sure I heard her giggling in the background.
