The pictured table is a 48 x 10 custom entry table of Texas rock elm I made for a Bay Area client, with 30" high 1/4" thick steel flat bar legs. The Lichtenberg figures are created by electrocuting the wood with high voltage, sending electrical channels burning through a baking soda and water solution brushed on to the wood surface. If I leave the figures in their natural black burned state and only do light sanding before the finish coat, I can maintain very fine detail of tree-like or coral reef patterns. To do colored epoxy inlays, enough sanding is required that I usually lose the finer detail and only maintain the larger channels so it's a more root-like pattern. The wonder of the pieces is that each burn is completely unpredictable and unique as to results, so each is very much one of a kind. Generally, the technique doesn't work very well with hardwoods and most people utilize softwoods and fine plywoods to do it, limiting it mostly to wall art use, but I've had surprisingly good results with hardwoods like Texas rock elm and mesquite and thus can apply it to fine furniture.
