To make beeswax crayons, grate an inexpensive bar of white soap, and grate or chop an equal amount of beeswax. Melt the beeswax and soap together in the microwave or in a double boiler. While the wax and soap melt, place 1/4 teaspoon liquid food coloring in the bottom of a disposable cup. Pour the melted wax into the cups, stir the mixture well to combine the coloring, and pour the mixture into a greased mini-muffin tin to cool.
If the colors are too light or too dark, adjust the amount of colorant added. To make multiple colors, pour the coloring in the bottoms of disposable cups, and add the desired amount of melted beeswax mixture to each cup.
If the beeswax mixture hardens too quickly to form a uniform crayon, place the mixture in the muffin tin and bake the crayons for a few moments at 325 degrees F.
Another option is to combine 90 percent carnauba wax and 10 percent beeswax and melt the waxes in a double boiler. Place the desired colorant in the bottom of a disposable cup, pour the melted wax over the colorant, and quickly mix the colorant into the wax. Pour the mixture into the desired mold. Options for colorants include earth pigments, food coloring or colored chalk.
