PHOTOCHEM Potassium Permanganate per 500gm (05526-0500)

Potassium Permanganate is a deep purple, crystalline chemical compound with the formula KMnO₄. It is a powerful oxidizing agent, commonly used in chemistry labs and various industrial applications due to its ability to react vigorously with many substances.

In photography, potassium permanganate has historically been used in alternative photographic processes, particularly in early photographic printing techniques like gum bichromate and carbon printing. Its primary role is as an oxidizing agent—it helps in contrast control and staining during the development of prints. Additionally, it can be used to bleach or tone photographic prints, subtly altering the image’s tone or preparing it for further chemical treatments.

Although it's not commonly used in modern digital photography, potassium permanganate still holds a place in historical and artistic photographic practices, appreciated for its unique chemical effects on print quality and tone.
