2. When the temperature of alkali solution drops to the same time as the indoor temperature, add waste oil and mix for 3-5 minutes.

3、倒入模具中（家里經(jīng)常用的，比方塑料盒、首飾盒等），3~5天就能夠凝結(jié)。

3. Pour it into the mold (often used at home, such as plastic box, jewelry box, etc.), and it will coagulate in 3-5 days.
