Salt-Making Journey

All background images and character designs were created by Jimeng AI.

The production of handcrafted sea salt involves a series of processes. Let's complete it together!

Step 1: Seawater Collection

Step 2: Evaporation

Step 3: Crystallization

Well done!

Thank you for helping me!

The traditional method of collecting seawater is to take advantage of the morning tide. When the tide rises, seawater will flow through an old water gate to the reservoir and then to the reservoir's sluice until the reservoir has been filled. When the weather is optimal, stored seawater will be pumped into adjacent pools for evaporation.

As the water evaporates, the salinity of the seawater rises. The average universal salinity of seawater is 3 Baumé degrees for cooking salt (namely NaCl). When the salt water reaches 28 Baumé degrees, Nacl become saturated and begin crystallize.

Frequent stirring is required during this stage to avoid uneven distribution of salt. Salt will begin to form leaving precipitation at the bottom of the pool. Salt farmers will use scraping tools suchas rakes to gather piles of salt. After draining the pile of salt, it is then transferred to basket containers and stored for furtherdrying.
