Royal Blue Color Block Dyes are one of Natures Garden's new candle dyes that can be used in a variety of our candle making waxes. Natures Garden's royal blue color block will help you create gorgeous blue candles and handcrafted tarts in a variety of blue shades. In the photo, you will see how we used a royal blue color block to create handmade wax melts. A single blue color block will go a long way. You will have enough candle dye to color around 15 pounds of candle wax in a deep shade. They will make coloring your candle a breeze. Just add a small piece of one of the solid royal blue dye blocks to your melted candle wax and mix the colorant completely. When adding the color blocks to candles, you can have specks of dye if not completely blended. Too much candle dye, including color blocks, can clog your wick which will inhibit the burn of your handcrafted candles. Each color block weighs approximately 1/2 oz. The royal blue color blocks are for use in handmade candles and wax melts only and should not be used in bath and body products.
