Spent all day baking...what you ask? Dirt. :-) I bought several cheap baking sheets at wal-mert. It went well, took almost all day, sifted it when I was all done, and added clay. Worst part was having to break it all up after I baked it.
It smelled the house up rather bad. Wife was not pleased, but that life, I could have used her good baking sheets. :-)
