Most of the shaping to the outside was carried out first until I was satisfied with the profile. Then the inside was carefully hollowed out, working progressively downwards to leave a thickness of around 3mm. After sanding the inside, a few final cuts down the outside were made to reduce the thickness to 2mm.
Rather than the very small voids most commonly produced by piercing, I chose much larger cut outs, which give a different effect and which were quicker and easier to smooth off, because a mini drum sander could be used to assist. In some of my pierced bowls I have included disguised names within the piercing pattern of pieces that were for anniversary gifts. For this piece I included a special void shape, that could easily be missed, unless carefully inspected.
The sycamore grain was very plain, so I decided to add colour. An airbrush was used for the outside, starting with blue, darker at the base and lighter further up, where it was blended with the red. Acrylic blue paint was applied by brush to the inside surface and to the inside perimeter of the voids. Darker blue was then applied with a sponge to provide a contrasting fleck appearance.
The rim had deliberately been left taller to add strength and minimise the risk of breakage. To finish, it was sanded down to a better level. The top edge of the rim, together with side and underside of the base were left uncoloured to show the bare wood. A finish of acrylic satin lacquer was applied.
