Any time you connect two pieces of clay together there is a joint.

Usually this is done by scoring or roughing up both sides of the parts to be joined, painting or dabbing on some thick mushy slip made of the same clay, pressing the two pieces together and then working the seam until it is well joined and smooth. Usually this is done when the clay is leather hard but it can be done when it is wet too. It cannot be done with regular slip it if it bone dry or bisque fired.

Then you need to control and slow it's drying and pray.

As the clay dries it will shrink, often about 10-12%. Smaller or thinner parts have more surfaxce area to volume and as they dry from the surface will shrink faster. This puts a great deal of strain on the joint and can cause it to pull apart. Covering it with plastic so it dries slowly will allow the clay parts to shrink equally and stay together.
