Barry at SurePure Chemicals, 5-W Nottingham Drive, Florham Park, New Jersey, 07932 has 99.999 ultrapure fine silver BUT it's not in a useful gauge, it's the size of a fine pencil lead. He is considering running some 14 gauge five-niner wire. If you're in the market, give him a call at: 1-888-377-3211 and please realize that I guesstimate that it will cost three hundred bucks for a foot of 14 gauge wire. Give him a call to check out the status of his production run schedule if interested. Otherwise, email C.C. Silver & Gold for a confirmed quote on much cheaper and highly acceptable four-niner 99.99 fine silver 14 gauge wire at: info@ccsilver.com or call 602-242-6301. God bless!
