Another Rib Repair

Here is another rib repair that Gordon has carried out. This time it was a large crack that had opened up in the bone that required filling. The deep cracks were first packed with polyether foam. A layer of ground cork mixed with B-72 (a conservation glue) is then spread over the surface of the foam. This is then covered with a skin of balsa wood 'flour' (finely ground balsa wood) mixed with B-72 to complete the fill.
