Rancho Gordo Tehuacan Clay Bean Pot (Unglazed) from Puebla, Mexico: Lead Free!

This is a rare find. A piece of Mexican pottery that is marked and sold as Lead-free that is ACTUALLY Lead-free. The reason for this is that it is entirely unglazed. I think this is a terrific option if you are looking for a bean pot or cooking vessel of this type and if I had a reason to use this I would have no concerns about using it in my home. The other metals found in the product are natural components of the clay.

What I really love about this piece is that it clearly contradicts what so many potteries argue … that there is always going to be a “natural” level of Lead in base clay for any ceramic items. That claim is simply not true.

When tested with an XRF instrument this (brand new) piece had the following readings:

  • Lead (Pb): Non-Detect
  • Cadmium (Cd): Non-Detect
  • Mercury (Hg): Non-Detect
  • Barium (Ba): Non-Detect
  • Chromium (Cr): 1,067 +/- 57 ppm
  • Antimony (Sb): Non-Detect
  • Selenium (Se): Non-Detect
  • Zinc (Zn): 92 +/- 14 ppm
  • Copper (Cu): 115 +/- 24 ppm
  • Nickel (Ni): 333 +/- 46 ppm
  • Iron (Fe): 67,400 +/- 1,000 ppm
  • Vanadium (V): 221 +/- 26 ppm
  • Titanium (Ti): 1,904 +/- 72 ppm
  • Magnesium (Mn): 631 +/- 128 ppm
  • Other metals not listed were not detected.

[Note: Test was done for a full 180 seconds (Three minutes) and repeated multiple times to confirm the readings. This is one full set of readings.]
