The present invention relates to a manufacturing method of high-temperature molten salt, which allows complete melting of salt to enable people to take only pure salt that is beneficial to the human body by removing harmful ingredients from bay salt, and to high-temperature molten salt manufactured by the method. According to an embodiment of the present invention, the manufacturing method of high-temperature molten salt comprises the steps of: (a) dehydrating pure bay salt and removing impurities (b) storing dehydrated bay salt (100) in containers (110, 120) for firing molten salt (c) laying the containers (110, 120) on a cart (132) of a melting furnace (130) (d) putting the cart (132) into the melting furnace (130) and heating the dehydrated bay salt (100) at a temperature of 600-750 deg. C for 30-120 minutes to firstly fire the dehydrated bay salt (100) (e) raising the temperature of the melting furnace (130) and heating the firstly fired bay salt (100) at a temperature of 800-1000 deg. C for 10-60 minutes to secondly fire the firstly fired bay salt (100) (f) lowering the temperature of the melting furnace (130) and heating the secondly fired bay salt (100) at a temperature of 600-750 deg. C for 30-120 minutes to thirdly fire the secondly fired bay salt (100) (g) gradually lowering the temperature of the melting furnace (130) for 2-5 hours (h) separating molten salt from the containers (110, 120) (i) grinding the molten salt which has been separated and (j) sorting and packaging the molten salt which has been ground by size.COPYRIGHT KIPO 2016본 발명은 고온용융(高溫鎔融)소금 제조방법 및 이로부터 제조된 고온용융소금에 관한 것이다.본 발명의 일 실시예에 따른 고온용융소금 제조방법은, (a) 순수한 천일염을 탈수하여 불순물을 제거하는 단계 (b) 탈수한 천일염(100)을 용융 소금 소성용 용기(容器)(110)(120)에 수납하는 단계 (c) 상기 용기(110)(120)를 용융로(130)의 이동대차(132)상에 층층이 적재하는 단계 (d) 상기 이동대차(132)를 용융로(130)에 장입하고, 600~750℃의 온도로서 30~120분 가열하여 1차 소성하는 단계 (e) 상기 용융로(130)의 온도를 올려서 800~1,000℃의 온도로서 10~60분 가열하여 2차 소성하는 단계 (f) 상기 용융로(130)의 온도를 내려서 600~750℃의 온도로서 30~120분 가열하여 3차 소성하는 단계 (g) 2~
