Raw materials: quicklime, sulfur powder and water, the ratio of these three kinds of raw materials is 1:2:10. Tanning method: Put the water in an iron pan to heat and boil, and mix the sulfur powder with a small amount of hot water into a paste, and slowly pour it into a boiling water pot, stirring constantly. When the water boils again, lime powder is added 3 to 4 times to the pot to stir and reduce the fire. After the lime is added, it is generally heated for 20-25 minutes to form a red-brown lime sulfur solution. It can be filtered and poured into the cylinder for use. The concentration of lime sulphur that is generally tanned can reach 1.21 to 1.26 g/l, and it can be 25 to 30 bm using a Baume meter. A Squid beard is the beard of a squid.
