A lot of people that follow me and read my blog or social media posts work in the Wet Collodion process. I’m amazed that so few working in Platinum Palladium don’t mix their own chemistry. It’s probably one of the easiest and simple things to do. The printing process is quite simple too. There’s no reason not to mix your own printing chemistry, especially if your working in, and mixing chemistry for Wet Collodion.
I made all of my chemistry today:
Ferric Oxalate: 55ml
Platinum: 25ml
Palladium: 50ml
Contrast Control: 30ml
Tween 20 (10%): 60ml
Hydrogen Peroxide (3%): 60ml
Potassium Oxalate: 1L (30%)
EDTA Clearing Bath: 1L (3%)
4.6 grams of Palladium and 3.2 grams of Kosher Coarse Salt - mixed in hot DH2O.
Getting setup - all of the equipment to quickly make up enough chemistry for many prints!
60ml Dropper Bottles for the “drop” chemistry.
Ferric Oxalate - the compound that triggers the platinum and palladium to reduce to pure metals.
