Buy Thermochromic Pigment Powder
Mixing ratios for thermochromic pigments are largely a matter of customer preference. There is no baseline standard for mixing into various mediums. The ratios below are recommended starting points, but can always be altered to taste. Remember, the less pigment you add to your medium the more transparent it will appear. The more pigment you add the more opaque it will appear. Adding more pigment to a particular medium especially more than 50% may alter the way the medium performs, dries, or sets. It is always best to test a small amount in a controlled environment before mixing a large masterbatch.
