That's a bummer, I thought you had information that I didn't. So it could quite conceivably be .1° or so small as to be immeasurable outside a laboratory.

Lead leeches into the solution whether you've anodized 1 square inch of surface area or 1000 square feet. |
I apparently didn't explain this thoroughly enough. I said that you aren't going to try to
get rid of it until you've anodized several hundred square feet. The point is that it doesn't pose a problem until you need it to go somewhere else. Unless you're staring at an LCD screen, the CRT monitor you're looking at right now contains lead, barium, cadmium, phosphorous, and mercury. While it's sitting on your desk it isn't a problem. If you throw it in a landfill when it dies, it becomes a problem. Likewise, the lead sitting in the bottom of the tank isn't a problem while the solution is in service - and
actually, we don't even know at what rate that's happening - it's quite possible that we're only looking at 1 ppm after 1000 square feet. I don't have a rinse tank. If my ano tank ruptured, I'd clean it up.

Well, I guess we'll just have to agree to disagree there. The only way my stuff would end up in the sewer is if the hazardous waste people put it there.

This is making my head hurt - probably in part due to lead poisoning, I'm sure. Bottom line is you recommend Al plates, I recommend Pb plates, and it sounds like both our alleys are safe [from us].
