The prepare continues to do ULF 16x20 wet plate. I purchased a 16x20 silver nitrate tank off eBay today from a seller in the Czech Republic. Cost of the tank was 189 GBP (325.44 CAD), with free shipping. I will use this tank to coat silver nitrate onto my collodion plates. I will be doing tintypes, ambrotypes as well as glass negs. This item seems to be well made, hopefully I can use it for many years.
