Default First time partial mashing with my 2 gallon cooler!!

Loved the process, reading threads here helped me prepare for it and I hit the right OG that I was looking for according to BeerSmith.

Only problem was that after cooling the wort down, I noticed the dreaded green stuff on the wort chiller and realized my whole batch was ruined.

Won't be trying again for a few weeks but I now feel confident about the process. Will probably be another year until I look into bigger pots, coolers, and burners for a full batch done all-grain.

Unless it was massive chunks coming off the chiller, I doubt that it was enough oxidized copper to really harm you. I did the same thing once running the wort through the chiller after letting it sit with StarSan for too long, the wort had a distinct green color for a little while when it came out, thought it was hops, then discovered on here that StarSan does a wicked pitting job on copper if left for an amount of time. Bottled it anyway and didn't taste anything off about it.

What green stuff. The green stuff on my chiller is usually hops from the boil.

I believe its called patina and I keep my hops in hop socks. It is toxic to humans.

Probably, but eh, I'm still breathing.

Yeah I usually have "green stuff" on my chiller right at the water / wort line of the kettle. No biggie, proceed...
