The present invention relates to a method of manufacturing an environment-friendly fishing weight. The purpose of the present invention is to strengthen the strength of a product of the fishing weight and enable the buoyancy of the fishing weight to be properly adjusted by preventing water from penetrating into the fishing weight through glaze treatment in manufacturing a fishing weight using environment-friendly materials to which a lead component is not added. In order to realize the purpose of the present invention, a method of manufacturing an environment-friendly fishing weight according to the present invention includes: a composition mixing step (ST 1) of mixing 30 to 50% by weight of clay, 10 to 30% by weight of white clay, 10 to 30% by weight of sandy soil, and 5 to 20% by weight of water a press forming step (ST 2) of injecting the mixed composition into a mold and forming the mixed composition into a fishing weight shape a natural drying step (ST 3) of naturally drying the formed fishing weight for 1 to 2 days a primary calcination step (ST 4) of calcining the naturally dried fishing weight at 800 to 850°C for 8 to 10 hours a glaze treatment step (ST 5) of dipping the calcined fishing weight into a glaze in which 40 to 60% by weight of water, 10 to 20% by weight of feldspar, 10 to 20% by weight of silica, 5 to 10% by weight of limestone, and 5 to 10% by weight of pottery stone are mixed such that a glaze coating layer is formed on the surface of the calcined fishing weight and a secondary calcination step (ST 6) of calcining the glaze-treated fishing weight at 1,200 to 1,300°C for 8 to 10 hours.COPYRIGHT KIPO 2016본 발명은 친환경 어추 제조방법에 관한 것으로서, 납성분이 첨가되지 않은 친환경 재료로 어추를 제조함에 있어 유약처리를 통해 수분의 내부침투가 방지되어짐으로서 제품의 강도를 강화시킴과 함께 어추의 부력을 적절하게 조절할 수 있도록 하기 위한 것이다.이를 실현하기 위한 본 발명은, 점토 30~50중량%, 백토10~30중량%, 사토10~30중량%, 물 5~20중량%를 혼합하는 조성물 혼합단계와(ST 1) 상기 혼합 조성물을 형틀에 투입하여 어추 형상으로 성형시키는 프레스 성형단계와(ST 2) 상기 성형이 이루어진 어추를 1~2일동안 자연건조시키는 자연건조단계와(ST 3) 상기 자연건조가 이루어진 어추를 800
