Diamond Dyes are super easy to use and NOT MESSY! Use 1 diamond per pound of wax for a medium color. Use less dye for a more pastel color and use multiple diamonds per pound of wax for rich deep colors.
It is very simple to get consistent colors with Diamond Dyes without a lot of fuss or mess. You don't need to shave off bits and pieces and they are neat and won't get everywhere like liquid dyes.
One diamond dye per pound of wax will create a medium to dark color in straight paraffin and a pastel in soy wax.
