Spread even on baking sheet and cook at 300 degrees for 1 hour. Also, Randy said that you can NOT overheat or cook to long. This process will drive off Co2 from the powder. GL

Baking soda is sodium bicarbonate. NaHCO3.

Washing soda = soda ash = sodium carbonate = baked baking soda = Na2CO3.

Spreading it out in less than a 1" layer seems to work better. I prefer to cook it at 400 degrees for an hour. You can't overcook it.

I agree with 400 degrees for one hour, but I always use a glass pan instead. My fear of picking up some metal from the baking sheet. I don't know if that would occur but better safe than sorry.

like a turkey, a thick layer will take a long time to heat up inside, but should still work if you wait long enough.

As soon as it cools a little, immediately store it in an air-tight container (big mason jar, mayo jar pickle jar, etc..),-glass container if possible so it doesn't absorb any moisture/impurities from the air or the jar (don't use plastic or metal containers if possible) - Baking Soda is probably the worlds greatest "odor eater" and this is why - it will absorb anything it comes in contact with, so it's important to store it air-tight in a totally inert container that can be cleaned to the level of sterility (like glass).
