Screen printing on ceramics is a fun way to get patterns and designs on your clay.
what you will need is:
Fine Fabric Mesh
Red Clay for a Under Glaze
Put your fabric mesh in the embroidery hoop. Draw your designs on the mesh then where you don't want the color to show paint it with the Mod Podge. Let it dry all the way.
Red Clay for under glaze you need to make it in to a nice slip.
Roll out your clay into a big slab.
Then place your embroidery hoop face down on the clay.
Get your red slip and paint the back on the mesh. don't use to much.
Repeat the pattern
Let the clay sit for a short time so the red under glaze has a chance to somewhat dry.
