Yes, it is possible to mix different waxes as they are generally miscible with each other. Wood waxes are typically made from natural or synthetic wax shavings and a solvent, with other components like pigments or natural oil added. Due to the similar basic components of waxes, they are easily mixed together. By combining beeswax and carnauba wax, a harder and shinier wax can be obtained, which provides better resistance to friction. It is advisable to keep records of your recipes for future reference when making your wax mixtures. Note that waxes that are already prepared (as opposed to raw waxes) can also be mixed together.
