When tested with an XRF instrument this Limoges floral pattern dish by Haviland & Co., Haviland France had the following readings:
On the food surface – with the scope on the flowers the center:
- Lead (Pb): 2,337 +/- 62 ppm
- Arsenic (As): 366 +/- 41 ppm
- Barium (Ba): 2,273 +/- 230 ppm
- Chromium (Cr): 212 +/- 91 ppm
- Tin (Sn): 104 +/- 36 ppm
- Zinc (Zn): 85 +/- 17 ppm
- Nickel (Ni): 60 +/- 19 ppm
- Iron (Fe): 1,675 +/- 87 ppm
- Bismuth (Bi): 60 +/- 25 ppm
This item was tested for a minimum of 60 seconds, and tested multiple times to confirm the results. Testing is done with an XRF instrument used in “Consumer Goods” mode. Results are science-based, accurate, and replicable. The XRF used is the same instrument used by the United States Consumer Product Safety commission for testing consumer goods for toxicity.
Why is this much Lead a problem?
For context (so you have a better understanding of what the above numbers may indicate): newly manufactured items intended for use by children are considered unsafe (and illegal) if the glaze, paint or coating is greater than 90 ppm Lead (as detectable with an XRF.) Dishware (modern and vintage) is not regulated in the same way (or with the same strict standards) as toys and other items intended for use by children. In my opinion dishware (which is also used by children) should be regulated in the same way (and with the same limits) as toys and other modern items intended for use by children.
I do not recommend ever using vintage china for food use purposes. Nearly every example of vintage china with a floral pattern on the food surface (that I have tested) has been positive for a very high level of Lead when tested with an XRF instrument.
