1. We prepare the water*-sodium NaOH caustic soda mixture.
We have taken all the safety measures (gloves, long shirt, mask and don't breathe the vapours!). We measure exactly the quantities. We put the distilled water in a plastic basin that can withstand high heat and add the sodium hydroxide, little by little, stirring with a plastic or wooden spoon. Never pour water into the caustic potash and never use hot water!!! As you stir, the temperature of the water will rise and the water will become clear. Allow the solution to cool and come to room temperature.
