To build a slab construction, you first need to roll
out your clay on the slab roller, place it into a plastic bag, seal it, and leave
it to set, dry up, and harden so that it will be able to stand. Slab construction,
in this case, must be at least ten inches high.
A week after, you can begin to cut out your template
of the construction you wish to make. After cutting out your template, it's
best to imprint your design now. I used a plumeria leaf as a design for my
slab. Now you will need to slice all the sides of the clay with a 45 degree
angle; therefore, when you combine all four pieces together, they will flush
perfectly together. Before applying slip to the sides of the clay, you must
score the edges so that the clay and slip will hold each other into place. Then
you can stand your pieces, and join them together. Carefully pinch the sides
together so that there is no cracks.
After it has been fired, you can begin to glaze the
piece. I glazed the leaf design with a satin-green glaze and then applied wax
resist. When the wax resist has dried, I dipped the vase into a yellow glaze, so
that the whole vase, including the inside, will be yellow. You will notice that
the yellow glaze did not mix with the green glaze because of the use of wax
resist.
In to the kiln it goes for firing one last time, and then my slab
construction will be finished.
