Generally speaking, the pigment ratio is a percentage of the entire mix so resin AND hardener.

Having issues on how much pigment to use I am using black so only using 5% but is it 5% of the combined resin and hardener thus being 25 grams of pigment or is it 5% of just the resin weight


I am using a 500 gram kit
