The color blocks can be used in soy and paraffin wax. They dye up to 5-15 pounds of wax depending on how dark of a color you would like. Just use a knife to shave a little or a lot of color into your wax. The shade can vary from picture and test first to achieve your desired color. The different colors (such as yellow & red=orange) can be blended together to achieve your desired color as well.
Color Blocks are made with colorant and paraffin wax.
