If you see Klay-On! Plus Polymer Clay is not softening even after conditioning, this could be due to poor storage or very low room temperature. The Softener is unpigmented clay which does not change the original clay’s color if used in small quantity. The Softener can be used with Polymer Clay for special techniques, e.g. Veneering, Mold-Filling, and Adhesion etc. How to Use: For best results, start with mixing a small quantity of Softener into your Polymer Clay and knead. Add more softener only if needed. You may need to add more softener depending on your climatic conditions. Use at most 1/3rd Softener in your Klay-On! Polymer Clay. Precaution: The Softener itself is tacky and flexible. If used in large quantity, it may cause your charm to lose shape and sharpness.
