My stirrer/hot plate should arrive today. A 320ppm batch will be my next project. Thanks for sharing all of your diligent work with us.
Tonight I'm stuck at the hospital watching over a buddy who just had knee replacement surgery -- he's reacting badly to the pain meds. It might be a few days before I get back on track, but I'll be watching for your results and will let you know how my batch works out once I get a chance to run it.
What's the consensus on using high concentration silver as an oral rinse? My wife just had minor oral surgery and is suffering with an infection in the surgical site. So far the 20ppm stuff doesn't seem to be helping.
Based on the info you just posted from Trapper, it shouldn't harm her even if she swallows it...
