Making of soap
Soap is very a useful thing in our daily life. It is prepared through a number of steps. First coconut oil and caustic soda are mixed with water. Then the solution (mixture) is heated for thirty minutes. Next the heated solution is allowed to cool. Thereafter common salt is added to the solution. The mixture is left for twelve hours. The mixture then solidifies. Thereafter, it is cut into pieces. Now the soap cakes are ready for use. At last they are sent to market.
