Oak chair naturally ebonised by breaking down some steel wool in vinegar. The resluting solution is appiled to a timber with high tannin content like oak and the reaction between tannin and potion turns the wood black. Danish oil is then applied to both protect the finish and to bring out the grain through the ebonisation.
A hide glue was used to assemble the chair, this allows a long open time for a complex glue up. It was also used traditionally to allow easy repair of older pieces by simply heating the joint to return the glue to a liquid state so a piece could be taken apart and reglued. This is where the chair gets its name.
Through, wedged and pinned tennons were used at the top of each leg to cope with stresses and racking. These joints were handcut and are also synonymous with traditional chair making, the back and seat are secured with wedged dowels.
Each curved rail is made from 9 pieces of oak that were first steambent and then laminated.
The chair is made from a single plank of oak local to the workshop that had a natural curve in the grain at one end which lent itself to producing a piece for the slightly angled back.
