The dark brown candle color blocks from Natures Garden Candle Making Supplies can be used to create a deep dark brown candle or even a lighter brown candle color. The picture shown above shows this brown color block in wax tarts in clamshell containers. A single brown color block can be used to color about 15 pounds of candle wax. They are to be used in candle wax only and are simply dyes dispersed in a wax medium. Ensure that your brown color blocks are fully melted in your wax before pouring your candle or wax melt. Too much candle dye can clog your candle wick inhibiting the candle's burn. If not fully mixed into the wax you can have specks of color in your finished candles. Each color block weighs approximately 1/2 oz. Not for use in body products.
