Location
Solar Sea Salt Production
Our solar sea salt production process is a meticulous blend of natural coastal heritage and technical precision. We harvest seawater from the Atlantic coast, allowing it to evaporate under the direct, consistent light of the Cornish sun. This slow, natural evaporation process ensures the retention of essential minerals and the development of pure, high-quality crystals.
• Seawater collection from the Atlantic coast
• Natural evaporation under Cornish sunlight
• Controlled concentration and crystallisation
• Harvesting and professional processing
Industrial Vacuum Salt
Our industrial vacuum salt production method provides a controlled, high-precision environment for consistent crystal formation. By utilizing advanced vacuum evaporation technology, we ensure that every tonne of salt produced meets the exacting standards required by commercial and technical industries.
From purified brine to final quality control, our process is meticulously managed to deliver salt with uniform crystal size and high purity. This industrial capability allows us to serve a wide range of professional applications with absolute reliability and technical precision.

Produced in West Cornwall
Inspired by the Coast
At Sharon Theiss Salt Production, we believe in the enduring power of natural processes. Our solar sea salt production is a direct reflection of the Atlantic environment, harnessing the sun's energy to evaporate seawater and create crystals that are as pure as the sea they originate from.
By focusing on responsible production, we ensure that our manufacturing practices respect the coastal heritage of West Cornwall. We utilise traditional evaporation methods that require no artificial energy input, relying solely on the natural rhythm of the tides and the sun to deliver consistent, high-quality salt to our commercial and industrial customers.
Company History
