PHOTOCHEM Sodium chloride per 1 kg (05541-1000)

Sodium Chloride (chemical formula: NaCl) is a common white crystalline compound best known as table salt. In photography, it plays a more specialized role, particularly in alternative and historical photographic processes.

In photography, sodium chloride is used in the preparation of light-sensitive emulsions, especially in early printing methods like salt printing. It provides the chloride ions needed to form silver chloride when combined with a silver nitrate solution. Silver chloride is a light-sensitive compound that darkens upon exposure to light, forming the basis of the photographic image.

Sodium chloride is essential for creating the photosensitive surface in these traditional processes and is valued for its simplicity and effectiveness in producing rich, warm-toned prints.
