From white salt fired into amethyst, how is nine-roasted bamboo salt made?

Clause. 1. The production process of bamboo salt is divided into eight times of calcination and one smelting, and it takes nearly two months to make the production cycle from beginning to end. In addition to rock pigments, the selection of bamboo tubes and loess is also very particular.

The bamboo tube is made of fresh moso bamboo that is more than three years old, and the loess is selenium-rich soil dug deep in the mountains. The workers first poured the salt into the mixing barrel, and after mixing it evenly with the brine, they began to fill the bamboo tube with salt. This tool seems simple, but it does not tolerate any horse goods, and the salt in the bamboo tube must be squatted to ensure the quality of the bamboo salt.

Next, after sealing each bamboo tube with loess, the first calcination process begins.

Clause. Second, the finished bamboo tube into the kiln, with these split pine wood as fuel, at a high temperature of 1000 degrees for ten hours, the instrument should observe the charcoal fire in the kiln in real time, to prevent the pine wood from burning out and causing halfway to give up. After the first calcination, the outer layer of bamboo has long been reduced to ashes, and the inner salt is mixed with the bamboo particles in the bamboo and the scent of pine wood, leaving behind this hard gray-white rock pillar, which is now to be mashed in a machine.

Clause. 3. Then use the method just now to repeatedly calcine the eight characters to let the harmful substances in the salt completely volatilize. In fact, when the calcination reached the third stage, it had already reached the standard of edible salt, and now it is the ninth smelting tool, and the temperature requirements are different from the previous eight characters.

Pour the bamboo salt into the furnace, light the firewood, and then stuff the pine juice prepared in advance into the furnace to increase the burning temperature to more than 2000 degrees, and then continue to smelt at high temperatures, the bamboo rock in the furnace gradually turns into magma, and as the smoke outlet slowly flows into this bucket, drag them to the safety boots, and after cooling in a static state for a night, they become this beautiful purple salt crystal. Finally, the workers slowly crushed, milled, drank and filtered, and the finished bamboo salt was finished here.

It is to extract some crystals from white salt, and then put them directly into the oven through the robotic arm and fully automated production line.

First of all, the white salt is calcined twice at a temperature of 80, then a little purple element is added, and then a little bit of solidifier is added with a drip tube, and it can be burned a few more times slowly.

The sea salt is loaded into the bamboo tube, put into the kiln for calcination, after calcination, the water of the bamboo penetrates into the salt water, and the bamboo salt becomes the shape of the salt stick, and then the salt gang is pulled out with a cart, and the salt stick is crushed with a blunt knife, and the obtained salt cup is put into the bamboo again for calcination, and each process of the bamboo salt must be completed manually, and the production time is often 30 to 50 days.
