Slab hump mould:
This is a similar technique to the slump moulds, except that we are using the clay over the mould instead of in the mould. Roll slab as in introduction, place it straight over the desired mould with a piece of newspaper between. The difference between the two techniques starts here, because clay shrinks, the form must be watched closely, and removed before it shrinks so much it cracks. When dry enough to handle, gently remove from mould and place rim down to dry. The piece is now ready for bisquing!
