When tested with an XRF Instrument this sewing / cutting / measuring guide (which belonged to a friend of mine who is a quilter) turned out to be painted with Lead paint in all of the markings on the guide.
This sewing tool had the following specific XRF readings
- Lead (Pb): 3,010 +/- 93 ppm
- Cadmium (Cd): 28 +/- 6 ppm
- Chromium (Cr): 5,410 +/- 261 ppm
- Silver (Ag): 13 +/- 4 ppm
- Palladium (Pd): 10 +/- 3 ppm
- Platinum (Pt): 156 +/- 50 ppm
- Zinc (Zn): 961 +/- 58 ppm
- Indium (In): 41 +/- 8 ppm
- Vanadium (V): 1,321 +/- 150 ppm
- Titanium (Ti): 11,700 +/- 500 ppm
The above test results are from a reading done on the side with the paint accessible (the yellow side). “For fun” I also tested this item on the other side (with the black of the writing visible) to see how diluted the reading would be if this Leaded paint were tested through the approximately 1/8 inch of clear plastic of the item. This is reminiscent of the way that an XRF can still read through vinyl siding on a house to the original Lead painted siding underneath – and I expect the relative differential in test results with siding (compared to the reading of what the original lead painted siding might be) is similar to this (an educated guess given most homeowners don’t want someone who is testing their home to remove their vinyl siding to test underneath to get a better reading!)

This is the “diluted” reading set – through the plastic:
- Lead (Pb): 699 +/- 21 ppm
- Cadmium (Cd): 31 +/- 3 ppm
- Antimony (Sb): 18 +/- 7 ppm
- Silver (Ag): 15 +/- 2 ppm
- Palladium (Pd): 12 +/- 2 ppm
- Platinum (Pt): 59 +/- 21 ppm
- Zinc (Zn): 57 +/- 10 ppm
- Indium (In): 41 +/- 5 ppm
- Vanadium (V): 55 +/- 25 ppm
