Into one of the bowls, add your titanium dioxide. For this technique, it's best to use oil-based titanium dioxide. Water-based will just not mix in very well.
The math
This batch had 52 oz. of oils...and made a 4.5 lb. batch of soap. I'm planning on the batch to be 1/2 blue and 1/2 white...so that means 26 oz. of oils and a 2.25 lb. batch of soap for each color.
For THAT measure, in the white bowl, I used 1 Tbs. of Titanium Dioxide and 1 Tsp. of Mica. In the blue bowl, I used 1 tsp. of Ultramarine Blue. (You may need to adjust this based on your colors, your taste and the size of your batches.)
Mix up the blue colorant in the second pyrex bowl. The Ultramarine Blue is oil dispersible. It will not actually dissolve, but it should disperse well into your oil. If it is still clumping after you mix it well, try adding a couple teaspoons of water to help mix it all together.
Set the two premixed oil/colorant bowls aside and get set up to mix your soap.
