These drawer pulls are from the dining set my grandparents got for their home when they were married in 1940 in San Francisco.
When tested with an XRF instrument they had the following readings:
- Lead (Pb): 8,681 +/- 643 ppm
- Cadmium (Cd): Non-Detect / Negative
- Arsenic (As): Non-Detect / Negative
- Mercury (Hg): Non-Detect / Negative
- Barium (Ba): Non-Detect / Negative
- Selenium (Se): Non-Detect / Negative
- Chromium (Cr): Non-Detect / Negative
- Antimony (Sb): 447 +/- 171 ppm
- Tin (Sn): 3,090 +/- 254 ppm
- Zinc (Zn): 293,100 +/- 2,700 ppm
- Copper (Cu): 688,700 +/- 3,600 ppm
- Iron (Fe): 1,636 +/- 303 ppm
I would expect any brass drawer pulls of the era to have similar readings for Lead.
Leaded brass items like this may or may not test positive with a LeadCheck swab*, the swabs were not really designed to test for lead in brass like this. So even if a LeadCheck swab looks “negative” your brass may still be positive for high levels of lead. You can usually tell by the color. Looking through my posts of different types of leaded brass items (link below) should give you a good sense of the concern and different examples.
