About Photographers' Formulary Ferric Oxalate

For professional photographers and printmakers, the 1L Ferric Oxalate (20%) from Photographers' Formulary is an essential component in various printing processes. This high-quality chemical is widely used in Kallitype printing, Platinum printing, Palladium printing, and Ziatype processes, making it a versatile addition to any darkroom.

Ferric Oxalate is also a key ingredient in iron-toning solutions, contributing to the creation of rich, vibrant tones in your prints. This product is light-sensitive, so it's crucial to store it in a light-tight container to maintain its effectiveness.

When it comes to making a palladium print, the paper is typically coated with a mixture of Sodium Tetrachloropalladate and light-sensitive Ferric Oxalate. It's important to note that while Ferric Oxalate is sensitive to light, Palladium salts are not, ensuring a stable and reliable printing process.

Whether you're a seasoned professional or a budding enthusiast, the 1L Ferric Oxalate (20%) is an indispensable tool in your photographic printing arsenal.
