Baked Baking Soda (Sodium Carbonate)

Bake, stirring the baking soda every half hour, until the weight of the baking soda is reduced to 613g (~21 oz), which is 2/3 of the starting weight (weigh the baking sheet with the baking soda, then deduct the recorded weight of the lined baking sheet to determine the weight of the baking soda itself). The amount of time this can take can vary quite a bit, anywhere from 2 to 5 hours.
