The amount of Sodium Silicate is about half the volume of the water. The total amount of liquid will be about 96oz for this batch. Mix it. No kidding, beat the heck out of it. Mix it completely and then mix it some more. You have to break up the kaowool. This is absolutely the most important thing there is to a successful batch.
