Lastly now for some problem solving. Looking at previous? forum reddish orange uranium glaze? xrf ? , The red color component is likely from Pb. Happy ending

Here is updated? xrf? for purple and yellow? mugs. Yellow is related to cadmium with selenium missing. Purple is cobalt with high zinc. Not Mr Mn as originally suspected,. Reflectance

Strong Cd and Se along with Ba on the Orange mug. Both mugs showing good correlation with the color table. Dud Sent: Sunday, January 12, 2025 6:31 AM To: [email protected] Subject: Re:

Here is another repeat xrf with? higher count rates Done for blue and orange mug for now. Blue show Co peak. Orange show Cd and selenium peaks? etc The color chart is a good indicator. Certain color

There are some rather high components in ceramics – PbO 24-34% by weight and up to 7% CdO in glazes (Nordyke 1984). However, leachability is low at a fraction of a ppm. Dud Sent: Sunday, December

Taray, I’m beginning to think this is not an escape peak but may be a peak due to Bragg scattering. To test that run 2 shots but change the angle of the X-ray beam to the target and see what happens
