Test what’s leaching from your pot: The Alkaline Baking soda Test - Archived
The Baking Soda test is an easy to do home-test to check the toxicity and leaching of metals and/or chemicals
You can do the Alkaline Baking soda Test right at home to check your pots/pans:
—Boil 1 glass of water in any pot, when it starts boiling add 1/2 tsp of baking soda. Boil for 5-7 more mins. Turn stove off.
—Wait till cool enough to taste then taste the water (take a sip). If you taste metals, that’s what you’re eating! If water has a rubber/paint taste it’s the chemicals from enamel/glaze.
As a control, stir 1/2 of baking soda to 1 glass of water take a sip — you will taste just the baking soda. When done in MEC, taste of water will be similar to taste of water in glass cup.
Baking soda is high on the pH scale (alkaline), with a pH value of 8. Most of the foods we eat are alkaline — an ideal diet is said to be at least 80% alkaline. If your pot leaches while cooking baking soda, unfortunately, it does the same with most of the food you cook!
