Usage: 1oz colors 100 lbs soy or 200 lbs paraffin to a medium shade. 4oz colors 400 lbs soy or 800 lbs paraffin to a medium shade. Fragrance Oil Recommendations: Apple Jack and Peel, Cinnamon Buns, Cinnamon Stick, Cranberry Marmalade, Macintosh Apples, Mulberry, Red Hot Cinnamon Deep, rich colors are difficult in soy. They require 2-3 times the dye that paraffin requires, sometimes more. Note that standard dye amounts create a washed-out, pastel color in soy. We suggest making a test swatch to figure out the dye amount you will need to get the color you'd like. Due to the extreme concentration of our liquid dyes there is a noticeable odor that will not be detectable at normal usages in finished candles. Product Update: We are converting our glass liquid dye containers to plastic containers for easier shipping. Made in the USA
