Using Negative Space - Segment Slabs


Well this is a slab of glass!! About 12 mm thick and 310 x 185 mm in size. It's not a complicated process but it is time consuming and needs three kiln firings and a glass saw so the final piece isn't cheap.

It's another Bullseye Glass technique which they have called a Segment Slab, a variation on the pattern bar technique. The segment slab is composed of sheet glass strips that are tack-fused together, cut into cubes, arranged with space between them and fired within a containment system until the glass flows and forms an internal pattern.

The key to the technique is arranging the cubes of tack fused glass within the stainless steel ring mould to take advantage of the fact that glass melts, flows and 'wants' to be flat. You can see in the bottom left how the five cubes have flowed into each other (the middle cube was placed rotated 90 degrees to the four surrounding it.

It's a cool technique but better suited to a commission statement piece than one offs because the price of the above plate is $200. Not high if you say it quickly!!
