1. Difference in baking process

* 9-time Bamboo Salt: Baked at 800℃ for 1~8 times, and then melted during the 9^th time. Uses resin when melting, and the temperature reaches over 1,300℃.

* Purple Bamboo Salt: Unlike the above 9-time Bamboo Salt, the baking temperature for the first 1~8 times is higher than 800℃. Therefore, some of the salt pillars start to melt during the 7^th or 8^th time of baking and they can show a purple color in the middle of the salt pillars.

Because it has to be hotter than 9-time Bamboo Salt, the more native pine trees are used for more care (burning, melting, bamboo charcoal processing, time, temperature, etc.).

For the last 9^th melting process, it is baked at over 1,500℃ which is higher than the melting process for 9-time Bamboo Salt, and also more resin and pine trees are used. Due to humidity and other conditions, it is more likely to fail than 9-time Bamboo Salt. Therefore the yield is not very good.

2. Different tastes

* 9-time Bamboo Salt and Purple Bamboo Salt taste differently.

9-time Purple Bamboo Salt has a more sulfur taste (egg taste) than 9-time Bamboo Salt, and many people prefer Purple Bamboo Salt for this reason

3. Differences in potential efficacy (Dr. Choi Eun-a’s opinion)

Purple Bamboo Salt is baked at a higher temperature than gray bamboo salt at each of the 1 to 9 times, so the more effective ingredients contained in bamboo are synthesized into the salt. The effect of bamboo salt does not increase when using more of the mixture of bamboo, instead it is from the synthesis of the ingredients in bamboo to salt through high heat. There are not many differences in the ingredients between room temperature water and boiled water (Baekbitang; boiled pure water) but the effects are different. So through experience, boiled water has been used in oriental medicine. Purple Bamboo Salt of Insan Bamboo Salt is made by taking into consideration the size of brazier and flocculation method taught by Dr. Insan, and adding the clean air of Jirisan Mountain (even the ingredients contained the air is different). Even for pine trees, the ingredients of native pine trees are added in bamboo salt along with the fire flames. Therefore, Insan Purple Bamboo Salt is a substance that all of Western sea bay salt as which all Korean earthly matters are condensed, iron pillar, red clay, native pine tree and pure air from Jirisan Mountain are concentrated. When the natural substances are dealt in oriental medicine, the trace elements are considered more important than just a quantity, which are the main ingredients. The effective substance comes from mostly trace elements, not the main element. The main element acts to assist these trace elements. The effects of bamboo salt changes not only because of the ingredients but also because of energy, electromagnetic, physical molecular structure and so on.

4. Reason that it is more expensive

Additional high-temperature processes involved in making Purple Bamboo Salt result in higher costs for raw materials, management, and depreciation, but also the entirely hand-made method, the same method that Dr. Insan, Kim Il-hoon used a long time ago, contributes to the expensive cost. It is not produced by automated mass producing facilities.
