About Photographers' Formulary Rochelle Salt

What sets the Photographers' Formulary Rochelle Salt apart is its impeccable purity and consistent high quality, making it an essential component for professional photographers and photography enthusiasts alike. This 100g pack of pure Rochelle Salt, also known as Seignette salt, is a testament to the legacy of Pierre Seignette, the La Rochelle apothecary who first synthesized it around 1675.

Crafted with precision, this reliable Rochelle Salt serves as a key ingredient in Fehling's solution, a reagent used by photographers to determine the presence of reducing sugars. Its effectiveness is not limited to photographic applications; it also plays a crucial role in the process of silvering mirrors, where it contributes to the creation of reflective surfaces by depositing a thin layer of metallic silver.

The high-quality potassium sodium tartrate offered by Photographers' Formulary is sought after for its professional-grade results. Whether you're developing photographic film, working with paper, or engaging in the meticulous art of mirror silvering, this product delivers consistent and effective performance.

Choosing this bulk 100g offering of Rochelle Salt not only ensures that you have a sufficient supply for your photographic or chemical needs but also provides the convenience of not having to frequently replenish your stock. Trust in the Photographers' Formulary name, a brand synonymous with excellence in the field of photography chemicals, to supply you with a product that is as reliable as it is indispensable.
