Vintage Ceramic Hull Brand (Made In USA) Coffee Cup: 299,800 ppm [30%!] Lead (when tested with an XRF instrument.)

Ceramic “Hull” Made In USA “Oven Proof” Coffee Cup.

When tested with an XRF instrument this cup had the following readings (each test done for a minimum of 60 seconds.)

Exterior Brown of Cup

  • Lead (Pb): 120,700 +/- 5,000 ppm
  • Barium (Ba): 498 +/- 145 ppm
  • Selenium (Se): 158 +/- 77 ppm
  • Iron (Fe): 17,300 +/- 1,000 ppm
  • Vanadium (V): 110 +/- 54 ppm
  • Titanium (Ti): 821 +/- 120 ppm
  • Magnesium (Mn): 24,100 +/- 1,400 ppm
  • If a metal is not listed it was not detected.

Mottled White Lip / Edge of Cup (image above):

  • Lead (Pb): 299,800 +/- 26,000 ppm
  • Barium (Ba): 1,234 +/- 391 ppm
  • Copper (Cu): 324 +/- 147 ppm
  • Iron (Fe): 8,559 +/- 1,101 ppm
  • Titanium (Ti): 687 +/- 173 ppm
  • Zirconium (Zr): 31,200 +/- 3,600 ppm
  • Magnesium (Mn): 9,435 +/- 1,369 ppm
  • If a metal is not listed it was not detected.

All Hull brand items I have tested have been positive for very high levels of lead. I would never drink out of these (especially not coffee!) and do consider this brand of pottery to be a potential significant exposure source (and health risk) if used as intended for food use purposes.

    Unbelievable…so shocking! I don’t understand why they do this. Is it just cheaper for them to manufacture?? I can’t wrap my head around this.

      Hi Ivanka,

      The Lead industry did a solid job of convincing other industries (like pottery and house paint) that Lead added beneficial properties to their products. This was especially true in times when there was not a war going on (and bullets were not being made and the Lead industry needed an outlet for their product) – so the 1950s – 1960s (when this cup was likely made) we were between wars and ceramics from that time tend to be very high lead. That also explains why paint between WWI and WWII is very high Lead (among the highest Lead paint one usually finds on homes.)

    Okay, and just how much of that lead leaches out into the beverage? If it does not leach out, it is not a problem.
