Hi Blanche! It’s generally considered not safe to eat eggs (or other food projects) after they’ve been involved in oxidizing or patina processes. You never know what kinds of toxins may have been generated during the patina process, and deposited on the eggs / other food involved. If it helps, here’s my easy tutorial for how to oxidize sterling silver and copper with boiled eggs.

In that tutorial I also mention “Don’t eat the eggs used in the oxidization process. Instead, boil a few extra eggs for eating when you boil the ones you’ll use for oxidizing your metal. 🙂 ”

I hope this helps! 🙂

I wonder now. If I have silver wire or findings I need to tarnish, and a batch of hard boiled eggs to make – if I toss the silver in with the eggs boiling (my household eats a LOT of hard boiled eggs! Cheap high-protein snacks for the kids) will it make the eggs toxic? I wouldn’t think so; my mom used to boil hers in a big aluminum pot, and none of us have medical issues related to that. 🙂
