The present invention provides a clay extruder having a reinforced plunger for shaping clay into desired patterns having a hollow core. The extruder has a screw disposed within a sleeve, a reinforced plunger located on the screw and inside the sleeve, a handle located on the screw and outside of the sleeve, an adaptor disk for forming a hollow core, and a perforated extrusion disk opposite the insertion of the screw into the sleeve. As the plunger pushes clay out the sleeve, an o-ring around the plunger prevents clay from leaking back, and the adaptor disk for forming a hollow core and a perforated disk mold the clay into a desired pattern with a hollow core.
