Clay Shrinkage During Drying and Firing | Preventing Defects

For a example, if clay shrinks 5% during drying, a piece of clay that is 5" long, will shrink 1/4" and a piece that is 20" long, will shrink 1" during the drying. This is why it is beneficial to know that the larger the piece is, the more important it becomes to let it dry evenly (slow drying will yield even drying).CIR495/EP004: Drying and Preserving Plant Materials for,,Drying is complete when flowers are crisp and dry to the touch, but not brittle.
