Colors are formulated to easily mix with one another but at the same time, maintaining their original sharp color shade with no visual smearing or bleeding. This clay contains pure beeswax and premium quality pigments and is condensation resistant. Easy to condition colors. Pardo Art Clay comes in true vibrant colors that are extremely strong and maintains color after baking.
