Motif and Relief - 3D

 For this technique, we used terracotta clay and rolled it into an equal levelled, flat, rectangle form, after this I carved a gear shape out of one side, this is called a motif, next to it and bigger, I built up the form of a gear, and finally I lightly carved lines into the background. once the modelling process was complete, I put it in the kiln to be biscuit fired, which allows the clay to be hard and absorbent enough for glazes, coloured glazes and iron oxide effect, but not hard enough to be complete. On this piece, I rubbed an iron oxide/water mix over it, and scrubbed it back off, leaving it dark in the hollow areas. I then used a black under-glaze colour on the gears, and only on the raised gear shape I used a clear glaze. Finally, it was placed back into the kiln for a final, hard firing.
