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、等到堿溶液的溫度在降到了和室內溫度差不多的時候，可以往當中添加進去廢油差不多再持續(xù)的攪拌3~5分鐘。

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.

氫氧化鉀

Potassium hydroxide

3、接下來需要倒入到模具中即可，在選擇模具的時候一定要選擇合適材料的，差不多3-5的時間即可凝固不過像是我們自己制作的，需要等到在凝結之后再風干半個月的時候才可以進行使用。

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、在制作的過程當中如果想要添加一些有顏色、香味等，也是可以根據(jù)相應的配方往當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、不過在添加一下物質的時候一定要注意控制好各種的計量，尤其是往當中添加的堿性物質劑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.
