No Arsenic, Lead, Cadmium or any other toxins in MEC's 100% Pure …

No Arsenic, Lead, Cadmium or any other toxins in MEC s 100% Pure Clay.

It was recently brought to our attention that an individual running a site called ireadlablesforyou.com had purportedly attacked the integrity of Miriams Earthen Cookware and the owner. Upon reading, we see that this individual has stooped low resorting to falsehood as she attempts to convince the reader that MEC s 100% Non-toxic, pure clay cookware could contain arsenic and/or other dangerous chemicals (despite all the proof we have to the contrary). And in its stead she recommends/promotes glazed cookware that has over 70 to 100 chemicals, toxins and additives including high levels of arsenic.

Here is a the article: Defamation of Character article on Miriams Earthen Cookware by Irena Webb.[1]

This falsehood she claims with no evidence or proof. The only link she cites talks about lead and arsenic in health drinks that could have commercial, factory processed, chemically extracted bentonite: http://www.nutraingredients.com/Suppliers2/Consumers-warned-of-arsenic-and-lead-in-health-drinks[2].

And the only reference cited has nothing in relation to her claim either, please see below:

  1. This study published in the journal Science of the Total Environment (vol. 409 (15) Jul 1, 2011) detailed the results of testing of glazed and unglazed clay cookware

Rebuttal: This publication referenced here says nothing about testing of glazed and unglazed clay cookware. Here is the link to the actual publication: http://www.sciencedirect.com/science/journal/00489697/410[3]

We know and appreciate that most of our customers/viewers and readers understand and know this difference, and we thank you for bringing this unscrupulousness to our attention. Based on your request we are addressing the issue here:

Miriams Earthen Cookware is a 100% Made in USA product and is made from:

(1) Clay that is 100% Tested Primary clay that has NO toxins & NO chemicals, and absolutely no additives are used in the making, finishing or firing of our products.

(2) Is fired to 2000 degree Fahrenheit, where the raw clay is turned into a rigid stone like entity that is 100% inert.

(3) And as for her claim that it has arsenic, given below is the complete test analysis from one of the most reputable, state certified testing laboratory in the country University of Massachusetts in Amherst (http://soiltest.umass.edu/[4]), evidence that refutes this falsehood. Here is an important piece of information about arsenic in clay soil: Arsenic is a sorbid metal, which means it is a metal not naturally found in primary clay, rather it is absorbed if exposed to it for a long time. This happens because of various human activities like fracking, mining or carless disposing of factory chemicals and toxins. Some toxins & chemicals used in farming could also cause contamination, but with primary clay, because it dries to a very rigid consistency in the summer, it does not support farming.

A simple search on Google/Bing for raw materials dictionary to make glazes and ceramic clay will show you the 100 or more chemicals used in ceramic bodies and glazes. See below a list in brevity.

Other statements of falsehood made on the article and rebuttal:

1. Image shown on the article

Rebuttal: the image she has shown is of item bought from the alternate line and with a steep discount. It does not represent any products from the regular line or the current alternate line inventory. You can find accurate images of products here: Miriams Earthen Cookware, pots and pans.

2. I studied the detailed instructions on how to season Miriam s Earthen Cookware pot and followed them. I was extra careful to follow all the instructions After seasoning the pot, the first thing I cooked in it was beef bone broth, which was not very convenient because the water evaporated even faster than from a stainless steel pot.

Rebuttal: Miriams Earthen Cookware s instructions clearly state that long hours of cooking should only be done in the pot after its been used a few times for shorter time periods of cooking. Obviously the instructions were not followed correctly.

Please read here:

When Slow Cooking

Use your pot for slow cooking or several hours of cooking once it s used at least a few times (4-5 times) cooking recipes that take less than an hour of cooking. Always use a diffuser when slow cooking with your pot.

3. The aroma of the broth mixed with the scent of clay remained in the house for a few days. Actually, after I ate the beans I continued having a clay aftertaste in my mouth for four days

We have sold several thousands of pots and pans but have not heard from one customer that the scent of clay remaining for days . Neither have we heard from anyone about any kind of clay aftertaste . Rebuttal: Over the phone she did state that she suffers from multiple health conditions and is on different medications, chemicals & supplements, which could have possibly triggered what she alone claims to have experienced. The individual also uses the article to promote some of those medications.

4. On her website, Miriam has a full list of nutrients and micro nutrients found in the clay[7]. This is different from a full list of ingredients that make up the clay. Miriam said that she has the full of list of the ingredients she uses, but it is proprietary information. Rebuttal: Another slanderous statement. The list on the page does contain the full list of ingredients in the clay.

5. And if you d like, please come by our house and take this clay pot from us because we do not know what to do with it. Unfortunately, Miriam s return policy is no return.

Rebuttal: Correct information on this slander:


If for some reason you are dissatisfied with your purchase, please call or email us and we will do everything we can to resolve/rectify the issue.

Customer can return the pot up to 3 months of purchase if unused. If it s used, and you re having an issue please reach out to us and we will try to resolve it in the best way possible. The pots are made to last forever, but if for some reason they happen to crack during use, (reasons include accidental misuse), we can send you a FREE REPLACEMENT for up to 1 year of purchase. Customer pays for replacement shipping charge which is $22.00 for domestic shipments and the freight charges for international shipments. If you accidentally dropped your pot and if it breaks, you can purchase another one at 40% off for up to 2 years of purchase.

6. Miriam suggested that I call the lab and ask for the test results directly from them. I did, but as you can imagine, the lab did not release any information to me as I was not their customer. Rebuttal: On the phone, she spoke to the contrary, she called back and said she changed her mind and choose not to call them.

7. I had learned clays have a variety of ingredients, from nutritious things like calcium and magnesium to potentially harmful things like aluminum and antimony. There is no antimony in any kind of natural clay, it is an additive used only in glazes and ceramics as fluxes.

As for the derogatory tone and defamation of my character, only history will tell who Miriam Kattumuri really was.

Thank you for reading and thank you again for all the support and encouragement through these years of hard work.

As said earlier, a search for raw materials dictionary to make glazes and ceramic clay will show you the 100 or more chemicals used in ceramic bodies and glazes:

Here are some of the raw materials that make up glazes and ceramic or porcelain clay:[8]

LEADED SILICA. CADMIUM: to obtain dark coloring and resist glaze penetration, IRON CHROMATE: FeO l Cr2O3 (m.p. 3000o F/1725o C) used in glazes (typically 3600o F/2000o C) is a Zircon opacifier used in glazes and slips VEE GUM T hydrated Magnesium Aluminosilicate. used as a plasticizer and as a suspension agent in glazes. VANADIUM PENTOXIDE V2O5 (m.p. 1270o F/690o C) is derived from Vanadium ores in. It is used in a glaze as a colorant in combination with Titanium. UMBER (Burnt) is Limonite (FeO.H2O) and Manganese Dioxide. RUTILE TiO2 (m.p. 3452o F/1900o C) is an economical source of TiO2 used in ceramic clay to promote and dark tans in oxidation, in glazes. PYRAX HS (m.p. 2790oF/1530oC) is a high Sericite (a fine grained muscovite mica; K2Ol3Al2O3l6SiO2l2H20) pyrophyllite blend produced (at this writing) by the R.T. Vanderbilt Company, Inc. It is made up of 35% foliated (platy) Pyrophyllite, 35% Quartz, 25% Sericite, and 5% Kaolinite. To increase strength in vitreous bodies. ALUMINA HYDRATE Al(OH)3 (m.p. 3722o F/2050o C) is used primarily in glazes as a source of Alumina. It is often favored over the oxide (Calcined Alumina) form due to its promotion of glaze adhesion and its capacity to remain suspended in a glaze. It is also used in salt glaze, bungs, and kiln wash. ANTIMONY OXIDE Sb2O3 (m.p. 1166o F/630o C) used in glazes as an opacifier and colorant (rarely, due to cost). However, its primary use is as a colorant (cone 06-1). In the presence of Lead or Iron, it will produce yellow. It is slightly soluble and very toxic. BALL CLAY is so named because it was first sold in England in the shape of a ball. It is a fine particle size secondary clay containing montmorillonite as its chief clay mineral constituent. It is also used as a source of Alumina in high temperature glazes (cone 8-13), and it helps to keep a glaze slip in suspension. BARIUM CARBONATE BaCO3 (m.p. 2480o F/1360o C) is used in glazes as the typical source for Barium. It is reactive and highly toxic. In low fire glazes (cone 06-5) it promotes matt (sometimes dull) finishes. However, at high temperatures (cone 8-13), it is a powerful flux. It is used in clay bodies to control scumming by rendering sulfates insoluble. BONE ASH 3CaOlP2O5 Bone Ash is prepared by calcination of selected animal bones (especially cow bones; some CaCO3 contamination) and then ground to a predetermined particle size. When Phosphate is added to a glaze it tends to cause opacity, too much is likely to cause crawling or blistering. It is used as a flux in higher fired glazes (cone 8-13), and also as flux in porcelain bodies where it is known to enhance translucency.
Synthetic: Bone Ash is produced from other non-bone Calcium Phosphate sources such as; the mineral apatite [Ca5(PO4)3 (OH,F)].
BORAX Na2Ol2B2O3l10H2O (m.p. 1366o F/741oC) also known as Sodium Tetraborate. Granular: Borax (5 and 10 mol.) has a coarse particle size (99.9%
