Classic Cerulean

For the traditional reactive dyeing process you will need dye powder, soda ash, urea (opt), fabric detergent (opt), dust mask, gloves, and safety glasses. Dye Mixing: For the swatch, we used 2 tsp Classic Cerulean Blue dye powder to 1/4 cup warm water with 1/4 tsp urea. You can use less dye powder to get a lighter hue or or more to get a deeper hue. [Classic Cerulean Blue (Blue - G) is a primary color.) Have fun dyeing!
