Clay has a memory. So in an effort to erase the memory of a crack, score the area in question deeper and larger than the crack itself (2), then place a bit of scored soft clay into the space you’ve made and compress it with a rib (3, 4).

How to strengthen air-dry clay when sculpting delicate parts, for example, fingers?
