Bark casting is a way to capture an impression of tree bark. A "casting" is something that's set (or "cast") into a mold. In this craft, the mold is made from clay. Bark casing is a great way to record and compare the bark patterns of different trees.
What You'll Need:
- Modeling clay
- Rolling pin
- Self-hardening clay
Step 1: Roll out a piece of modeling clay into a flat sheet.
Step 2: Press the clay onto a tree trunk -- press hard enough for the bark to create an impression in the clay.
Step 3: Carefully peel the clay off the tree, keeping the molded texture intact.
Step 4: To make a permanent cast of the tree bark, roll out a piece of self-hardening clay. Flatten it into a sheet the same size as the modeling clay impression you made.
Step 5: Place it on top of the modeling clay, and gently press it onto the ridges so that it captures all the textures but does not erase them.
Step 6: Gently lift off the clay and let it dry for two or three days. Do this for several types of trees, and compare the different textures.
