Paper Slip


Paper slip is a good solution for surface tension cracks.  If you are experiencing cracking in your process, a small amount of paper can help your situation.

It is important to note a couple of things:
Adding paper to clay may strengthen it while wet, bone dry and during firing, but may weaken it in the final fired state.
If the paper is not disintegrated well it can add texture, you may or may not want this.
Paper will rot, and smell.
Paper added into slip can make it very difficult to re-sieve.

For the above reasons, I recommend using the minimum amount necessary, and to mix paper slips in small amounts at a time to negate the need to re-sieve that batch of slip.

Use cheep toilette paper.  It has less glue and breaks up easily.  Tear it up very small, a food processor can work great on dry paper.

For a gallon of slip, 15-20 squares can be plenty.

Add it to warm water with a tea spoon of vinegar.  I like to let it sit over night. Blend it with a hand blender until paper is completely dispersed in the water.  Then just add to well sieved slip, blend well, and use as normal.
