actually the one in the picture here is brass with copper plate. but i think that the reason for the copper plating is because the proper construction material is copper.
it's actually quite hard to find pure copper cups. copper plated is probably adequate tho.
There are copper overload medical conditions but these rarely come up. I don’t think it’s excessive intake related either.
I think less severe forms of copper overload are underappreciated. I personally did substantial testing and finally put pieces together to form a hypothesis that my easy bruising was caused by copper excess (not noted on common lab testing) causing functional vitamin C deficiency. By taking zinc supplements and vitamin C supplements along with bone broth the bruising went away. Note that while on an almost carnivore diet including organ meats I continued to have substantial bruising. So I now am biased by personal experience but with that bias I see it every once in a while in practice. I personally won't be drinking from any copper utensils.
I’ll have to look in to copper deposition disease. I see iron deposition on MRI, but copper hasn’t come up in my experience thus far.
Apparently it’ll never come up in my world. At least not on MRI. Copper is not ferromagnetic, of course…but apparently copper can be both diamagnetic and paramagnetic with very little net effect in-vivo. So little effect it’s called non-magnetic.
Looks like you don’t need a radiologist to see copper deposition. Kayser-Fleischer ring in the 👁️
