What’s in your MEC clay? Test Results

Knowing what your cookware is made of is just as important as knowing whats in your food...

...because this determines whether your cooked food is really nutritious & potent or if it's half dead and contaminated with toxins.

Miriams Earthen Cookware is made from 100% Pure & Primary clay, the highest quality natural clay, harvested from non-industrialized and secluded places and tested in an independent US state laboratory. They're Tested to have No Lead, No Cadmium, No Arsenic.  They are 100% unglazed and NO additives are used in any of the making, finishing or firing processes. 

Here are the steps we take to ensure the purity of our clay:

Before the clay is harvested research is done to see if any industries or farming has taken place on the land in the last 200 years. It is also verified that there is as of the present and in the past no industries in the 15-mile radius around the clay dig site. This ensures that there are no toxins or pollutants in the soil.  Next, several samples are taken and sent to the laboratory to be tested for a 2nd level of confirmation to make sure the clay has no contaminants.  Then we harvest the clay.  The cooking pots and pans are formed by hand without the use of ANY additives or chemicals. 

And no, we don't know of another company that goes through these steps to get you the healthiest cookware.  If you know of one and if they're prices are lower please reach out to us and we can match their price.

Here is the Complete list of Nutrients & Micro-Nutrients in the Pure-clay:

Nutrients: Phosphorus (P), Potassium (K), Calcium (Ca), Magnesium (Mg)

Micro-nutrients: Boron (B), Manganese (Mn), Zinc (Zn), Iron (Fe)

Our clay is so pure it's edible.  And yes, they're the same nutrients that nourish and grow your food. 

Since it's just the way they're present in nature, and because nothing is added, nothing leaches out.  By the end of the process of making the pots/pans, the ingredients bind together to form a 100% non-reactive, inert cooking pot. A pot that cooks your food with a unique form of far infrared heat distributed evenly.  And by locking steam and preserving all the nutrients and flavor.
