Hi Amesmassage, https://connect.mayoclinic.org/member/00-7d4f3486919d1545236515/?utm_campaign=hub_email&utm_source=email&utm_medium=reply_intro_userlink
I've only been working in silver and copper for about 7 years. Before that I was a potter for 45 yrs. (There's where a lot of toxins are.. esp in glaze chemicals). My wrists got bad from pushing stiff clay in 2010 (I liked thin walls) and I had to give it up. Began the jewelry ~2014. I don't do enough for it to adversely affect me. Could not make a living at it. It's a craft that earns a few $$. I sell in 2 art galleries and a resort gift shop & do 3 local indoor shows/yr which were all canceled last year so have not made anything since Feb 2019. This isn't from inhaled or skin absorbed toxins. Thanks for caring enough to write and suggest it.
