#Leaded: Johnson Bros. Willow England Saucer, post 1912

This vintage Johnson Bros. Willow pattern shallow bowl/ saucer (made in England), was likely made after 1912 (based on the back mark, source.)

As with nearly all of the Willow pattern china I have tested, it was positive for very high (unsafe) levels of lead when tested with an XRF instrument. In general I would recommend not using these dishes for food use purposes, ever. [More info about the concerns here.]

If you have more information (or links) about dating the piece (based on the back mark) please let me know!

The test results for this particular dish:

  • Lead (Pb): 43,100 +/- 1,700 ppm
  • Mercury (Hg): Negative (ND/ non-detect)
  • Arsenic (As): Negative (ND/ non-detect)
  • Cadmium (Cd): Negative (ND/ non-detect)
  • Tin (Sn): 99 +/- 24 ppm
  • Barium (Ba): 424 +/- 93 ppm

As always, please let me know if you have any questions!
