All testing was done for a minimum of 60 seconds per test using a non-radioactive source (tube-source) XRF instrument specifically designed for testing for the presence of toxicants in consumer goods. Test results are science-based and replicable.
For context; Lead:
The amount of (XRF detectable) Lead that is considered toxic (and illegal / unsafe) in a newly manufactured item intended for use by children is anything 90 ppm Lead or higher in the paint, glaze or coating.
For context; Cadmium:
The amount of (XRF detectable) Cadmium that is considered toxic (and illegal / unsafe) in a modern item is anything 40 ppm or higher (when looking at Washington State regulations) and anything 75 ppm or higher (when looking at the regulatory standards implemented in the Country of Denmark.)
Vintage painted glassware like this should not be considered safe for food-use purposes. If you have something like this and intend to hold on to it, please display it behind glass – for decorative purposes only.
As always, please let me know if you have any questions.
