1925 German Altwasser Carl Thiersch (Silesia) saucer – Style # 2241: 6,410 ppm Lead on the food surface (decorative edge.)

Introduction:

Tamara Rubin is a Federal award winning independent advocate for consumer goods safety and childhood Lead poisoning prevention. She is also a mother of Lead-poisoned children. She began testing consumer goods for toxicants in 2009, and was the parent-advocate responsible for finding Lead in the popular fidget spinner toys in 2017. She uses XRF testing (a scientific method used by the Consumer Product Safety Commission) to test consumer goods for metallic toxicants (including Lead, Cadmium, Mercury and Arsenic).
