Top: solid hardwood, glued up into a full two-metre circle, stained to a warm walnut colour and finished with a hard-wearing varnish that wipes clean. At the centre, a 73cm disc of 10mm toughened smoked glass sits flush in a rebate in the timber, so plates and glasses sit level across it.
Base: ribbed steel rebar — the reinforcing bar that goes inside concrete — cut, bent and welded into the twist by hand, then clear-coated to keep the dark mill finish and rolled texture of the steel. No two bars are the same and the base isn't symmetrical; that's the point of it.
Care: wipe the top with a damp cloth and dry it; use mats under hot dishes. Clean the glass with ordinary glass cleaner. The steel just needs a dust — the clear coat protects it indoors.
