Extracting sea salt, compared to the previous firing of porcelain, basically involves no technical complexity. The evaporation crystallization method, the simplest method in chemistry, simply involves using seawater instead of crude salt......... All that is needed is to wait for the seawater in the iron pot to evaporate, then promptly add new seawater to ensure that the refined and precipitated sea salt does not burn. Dilan and his team do not have a filtration system, so the final product of sea salt might not be very clean, but considering their current living conditions, it's quite satisfactory. Having some is much better than having none. The wait is long, and everyone's eyes are filled with anticipation. This is make or break. Raindrops have already begun to fall from the sky.
