Foster’s Ferric Oxalate 20%, 28% and Potassium Chlorate 1%

Fred Foster’s original formula now available for platinum/palladium printers

Foster’s Ferric Oxalate 20% and 28% is for sale for platinum/palladium and kallitype printing. 100ml of 20% solution, US $39 plus shipping, 100ml of 28% solution, US $48 and Potassium Chlorate 1% US $14, plus shipping, Euro € prices at the current exchange rate and tax where applicable.

This ferric oxalate production method yields an extremely pure compound resulting in a greatly extended shelf life.

Store in a dark, cool place. Preferably in a refrigerator not used for food and out of children's reach. I recommend replacing ferric after two years, but have used three year old sensitizer with flawless results.

There are several payment options: in € or US$, via PayPal or wire transfer. Contact me at cpr [at] curtrichter.com to place an order
