Glad to hear it. I sure you'll be extremely pleased with the addition of a stirrer in that it will prove invaluable in the production of the most advanced Colloidal Silver made today. To which I'd add, will run circles around such products as Mesosilver and other equivalents.
That said, on the production method, I'd invite you to contact me via PM when you have your equipment and I'll guide you through the process.
PS. let me know if you need any help purchasing a good stirrer. I've been working with these a long time, and might help you avoid some pitfalls along the way.
