PURPOSE: A method for manufacturing natural calcium liquid is provided to obtain calcium liquid with alkaline concentration of pH 6-10 by adding water into calcium powder which is obtained by pyrolyzing shells based on heat of a high temperature.CONSTITUTION: A method for manufacturing natural calcium liquid comprises the steps of: putting pulverized and dried shells into a jar type heating furnace (1) covering the heating furnace with a cover (2) having air holes (2a) obtaining white calcium powder by pyrolyzing the shells at 1100-1300°C removing impurities from the white calcium powder by filtering the white calcium powder with a fine net and obtaining calcium liquid by mixing 0.04-0.08 weight% of the calcium powder with water based on the amount of water. The alkaline concentration of the calcium liquid is pH 6-10.COPYRIGHT KIPO 2013본 발명은 천연 칼슘액의 제조방법에 관한 것으로,패각을 세척하여 취급하기 쉽게 파쇄한 후 건조시켜 항아리형 가열로(1)에 넣고 통기공(2a)이 있는 뚜껑(2)을 닫아 1100∼1300℃로 가열하여 열분해방법으로 백색의 칼슘가루를 얻고 이를 여과하여 불순물을 제거한 다음 상기 칼슘가루를 물에 혼합하여 천연 칼슘액을 제조하는 방법이다.
