Marc,
When it looks white, it is dry, unless it has all
turned to carbonte which is unlikely. Pure anhydrous NaOH is white in appearance
and becomes more translucent as it absorbs water. Exposed to the air long enough
it will liquify.
Hope this helps,
Bill Clark

I have a questions before i want to start with making my first test batch
with the single stage method.
I bought NaOH from a hardware store, but it looks white so it is not
pure. Does somebody know how i can mesure the moisture content of this NaOH so
i can compensate for all this water?
(I can use an oven at my work that can reach 1000 degrees
Celsius).
Greetings,
Marc
