Making Tubing with an Extruder

by Janet Alexander
Technical Advisor

An extruder allows you to make different shapes of even thicknesses in clay very quickly. It's also great for makign clay tubing. Use the tubing for hollow bails, hinges, stone settings, or anything else you can imagine.

This is an aluminum extruder that is anodized with green paint. It is not advised to keep the fine silver metal clay in the extruder for very long, as this can cause a reaction with the clay. A very short amount of time however, does not cause a reaction.

Note: These extruders also come in a stainless steel version.

 The tubing attachments include a circle disc and a strange looking disc with a protruding nose (here, the Makin's ClayCore Adapter.)

Choose the a disc with the circle large enough to allow space for the clay to extrude around the tube disc's nose.

Here is the order in which the parts fit into the extruder. The cap, rubber ring, circle disc, tubing disc, clay, and the extruder body. 
Note that the tubing disc's nose points through the circle disc.

The Steps:

Twist the extruder's handle counter clockwise making the plunger slide into the body of the extruder. 

Roll your metal clay by hand into a ball so it fits inside the extruder. 

Place the tube disc into the extruder.

Place the rubber ring into the cap.

Place the circle disc in the cap. 

Attach the cap to the body. 

Extrude the clay into a tube by holding it perpendicular to the table and evenly twisting the handle clockwise. If you start and stop while twisting, the tube will not be even or uniformly shaped.
