Um, I know the winking smily wasn't around in medieval England, but surely you know what it means.
DANGER?? Mouthpieces contain dangerous amounts of LEAD?

In other news, I am an idiot. Large-scale electro-refining of copper is a thing, and has been for quite a while. Should have known better, having handled chunks of the stuff, looking like chopped-up pieces of wire as thick as my thumb, while temping in the labs of a photo-resist manufacturer. That's where I learned that putting one foot up on a low rail could relieve sciatic nerve issues, while spending hours standing around a process tank.
And I probably used your photoresist when I worked in a Printed Circuit shop.
Those chunks were copper for anodes in a plating tank. Easy to use copper with any insoluble contaminant for that process.
