Ordinary pieces can become quite extraordinary when we add texture in them! The most common way to make texture is by impressing various objects into the clay. One of the ways is by using plaster slabs and carving patterns on to it.
I started by joining four pieces of wood into a rectangle frame and reinforce and connect the joints with clay into the sides and edges. Place the frame in the middle of a clean sheet of glass.
Measure the water first when mixing, and put it in a plastic bucket . I Sprinkle the plaster lightly and slowly into the water to prevent it from clumping (for me its always messy this part lol). Stir the mixture by hand. The stirring should be done in such a way as to agitate the mixture and drive out air bubbles. It´s important to not whip or whisk the mixture. The point is to get the air out, not in. A good method of stirring is to put the hand, palm upward, on the bottom of the pail and wiggle the fingers vigorously. I Continue to mix for two or three minutes until i felt the plaster begin to thicken.
