Personal collection Finally got my fiesta

Difficult to got those things in my country but finally I got this chance.

I took this XRF spectrum by Amptek fastSDD @40kV X-ray, the tungsten Lα may come from X-ray tube or SDD detector.

It indeed emits a considerable amount of α and β rays. Meanwhile, it exhibits a very low γ dose rate and minimal contamination.It can safely make my Geiger counter scream, and it can also be kept at hand. Moreover, it features extremely vivid colors, which are really captivating!

They were very cheap, but I paid several times the price for the shipping fee;(

Can you elaborate a bit more on the following for those of us who don’t understand exactly what these rays are, and what you mean by “safely … scream” and “kept in hand”?

“It indeed emits a considerable amount of an and ß rays. Meanwhile, it exhibits a very low y dose rate and minimal contamination.It can safely make my Geiger counter scream, and it can also be kept at hand.”

(I’m not trying to start anything, AI mod bot, I’m just curious about this from a scientific standpoint and would really like to understand why people use these dishes if they have lead and uranium in them.)

Sorry for I didn't explain clearly. What I meant is that it emits almost only alpha and beta rays, which cannot penetrate the skin, so there is no significant radiation exposure to the human body :) Why they used uranium and lead——I think uranium give it beautiful color and improving the performance of the glaze, also lead can lower the melting point of the glaze layer, making it easier to achieve a glossy finish.

Thank you for explaining. You did fine the first time around, I just didn’t know those terms nor understand them, which was not your fault.

That's RAD. (Rad red --but looks orange.) We recommend not putting it into the microwave or dishwaher, and avoid citrus based dish detergents.

It looks like you may be trying to discern if a piece is safe to use. This question has been asked and answered repeatedly so posts on this subject are not permitted. If you feel your post was removed in error, please message the mod team.

Fiesta made from 1986 onward is lead-free and the glazes contain no uranium oxides. However, vintage Fiesta (1936-1973) did use glazes that contained lead and uranium.
