Sunday salt

In the salt pans, a special form of table salt was called Sunday salt . After the furnace was stopped under the suction pans ( salt pans ) after the end of the shift on Saturday until work was resumed on Monday, but also after public holidays, the salt crystallized into larger, grainy crystals undisturbed from the brine. The salt was particularly suitable for preserving meat and fish. The dissolution of the salt crystals due to the moisture in the goods was greatly delayed. Not all salt pans produced this form of salt.

The Sunday salt was also obtained from the brine of sea water, but differed in composition.

• Scottish sea salt per 100 parts: 93.55 table salt; 2.8 hydrochloric bitter earth , 1.75 Epsom salt ; 1.5 gypsum and 0.4 insoluble residue
• from the general brine to 100 parts: 97.5 table salt: 1.15 hydrochloric bitter earth; 0.45 Epsom salts; 1.2 gypsum and 0.1 insoluble residue
