I do not purchase Nurture's TD even with the great reviews, it is extremely expensive. I pay around $9 per lb for my oil td. Oil td is more work but I make up around 6 oz at a time in glycerin. Mix well and let it sit a few days stirring periodically. Eventually most will dissolve and the undissolved will stay on the bottom of my jar. To mix it I use a single whip on my hand mixer for mixing. Water TD just does not work well for me and I use quite a lot of TD
