Optically Clean® Technology

SaltWorks® Optically Clean® technology distinguishes our sea salts as the purest on the market.

Optically Clean® Certified - Pure Ocean® Sea Salt

Committed to providing pristine, unadulterated salt, our proprietary Optically Clean process eliminates all foreign materials and flawed crystals, while leaving the raw salt just as natural as the day it was harvested: no washing, no chemicals and no tampering with Mother Nature’s components.

Depending on its natural environment, sea salt inherently contains traces of foreign materials, like sand, shells, rocks, seaweed, or clay. Of course, none is harmful, but these elements can be especially unwelcome or problematic for many applications.

The Optically Clean Process

At SaltWorks, we ensure ultimate purity by running the raw salt through a proprietary combination of sifters, aspirators, rare-earth magnets and metal detectors. This process detects and filters the unwanted materials from the salt. After this initial screening, the salt is ready for the most thorough process: the Optically Clean technology, a highly innovative operation developed by SaltWorks that inspects every single grain of salt for discoloration or any remaining unwanted foreign material.

The quality of salt can be determined by its color—most commonly, the whiter the better. However, some varieties carry specific trace minerals that give grains a uniquely beautiful color. On the contrary, undesired materials can affect the color as well. Our Optically Clean technology keeps the desired colors that are high in trace minerals, while removing the less desired colors.

With high-definition color CCD cameras, UV lights, air jets and a very fast computer processor, color sorters detect micro defects and remove the flawed crystals. As the crystals cascade from a chute, the CCD cameras capture images of the crystals from both sides. When a camera captures a defective crystal, its location is calculated and the unwanted crystal is removed with a single blast of air. Even a single particle—smaller than a grain of sand—can be targeted and removed.
