1620

First attempts at mining

The first attempts to obtain thermal salt from the Karlovy Vary springs.

At the beginning of the 17th century, local residents and businessmen noticed the high mineral content of the famous Karlovy Vary thermal springs. This was the beginning of the industrial extraction of medicinal salt, which later made the entire region famous far beyond the borders of Bohemia.

1739-1769

Period of prohibition

A 30-year ban on salt production due to fears of a decline in visitors to the baths.

Local authorities and spa operators feared that industrial salt extraction would damage the natural springs and weaken their healing effects. The ban was introduced to protect Karlovy Vary's reputation as a leading European spa town.

1882

Technological revolution

Modernisation of production technology under the leadership of Ernst Ludwig.

Ernst Ludwig, a well-known German engineer and entrepreneur, introduced advanced methods of evaporation and salt crystallization. His innovations significantly increased the purity of the product and the production volume, while preserving the unique healing properties of Karlovy Vary salt.

1920

Scientific recognition

Exponential increase in popularity due to proven therapeutic effects.

After the First World War, medical studies confirmed the healing effects of Carlsbad salt in digestive tract diseases. The product gained official recognition in medical circles throughout Europe, leading to a sharp increase in demand and exports.

2006

Extension of the product range

Extension of the offer to mineral baths with aromatic ingredients.

The company has responded to current trends in the wellness market by creating a range of home care products. Salts with natural essential oils of lavender, eucalyptus and other herbs were developed - preserving the mineral properties of the Karlovy Vary springs.

2011

Modernisation of production

Extensive modernisation of the plant and transition to the current production standard.

Investments of €15 million have enabled the introduction of automated quality control systems, environmentally friendly production technologies and modern packaging lines. The result was compliance with international ISO standards and a significant increase in capacity.

2024

Innovative recipe

Introduction of a new formula with an emphasis on naturalness and health benefits.
