Richard has added reinforcing brackets at intervals around the perimeter of the armature according to the drawing to strengthen the whole armature and create a structure to support the bark of the plank.
Next, I began wrapping every inch of steel with copper foil. See the ribbon-like perimeter with it’s reinforcing brackets.
I used 1/.4″ thick glass cut with an irregular chamfered edge to represent the outer cambium layer of the plank (between bark and wood). I wanted this to be flush with the surface of the glass panes. Concertina-like strips of bronze fill cavities in the armature to support the bark.
And here’s the glasscutting almost complete. I was engrossed and didn’t take photos…
Jason was excited to see the glass laid out over his drawing when he arrived on Thursday to start cutting masks for the sandblasting. Each pane was then sandblasted to create an incised area that was painted and kiln-fired with black glass stainers enamel.
