1. First of all, we need to pour alkaline substances into water, and then stir it into alkaline solution without solid. In this process, we must pay attention to avoid getting potassium hydroxide on our skin, because alkaline substances have strong corrosive effect on our skin.

2、等到碱溶液的温度在降到了和室内温度差不多的时候，可以往当中添加进去废油差不多再持续的搅拌3~5分钟。

2. When the temperature of the alkali solution is almost the same as that in the room, waste oil can be added into it, and the stirring can be continued for about 3 ~ 5 minutes.

氢氧化钾

Potassium hydroxide

3、接下来需要倒入到模具中即可，在选择模具的时候一定要选择合适材料的，差不多3-5的时间即可凝固不过像是我们自己制作的，需要等到在凝结之后再风干半个月的时候才可以进行使用。

3. Next, we need to pour it into the mold. When choosing the mold, we must choose the right material. It can solidify in about 3-5 minutes, but it's like we made it ourselves. We need to wait until it's condensed and then dried for half a month before we can use it.

4、在制作的过程当中如果想要添加一些有颜色、香味等，也是可以根据相应的配方往当中添加色素或者是香精。

4, in the process of production, if you want to add some colors and fragrances, you can add pigment or essence according to the corresponding formula.

5、不过在添加一下物质的时候一定要注意控制好各种的计量，尤其是往当中添加的碱性物质剂量是一定要控制好的。

5. However, when adding some substances, we must pay attention to control all kinds of measurement, especially the dosage of alkaline substances added to it.
