Yaley-Concentrated Candle Dye. After your wax is completely melted, shave some of the dye blocks into the melted wax and stir well. To get an idea of the color concentration, place a few drops of wax onto a piece of white paper. The wax will immediately set up and give you an idea of the color of your candle. You can add more dye to reach your desired color. This package contains one 2×3/4×1-1/2 inch block of concentrated candle dye (.75OZ). Comes in a variety of colors. Each sold separately. Made in USA.
