3 CONCLUSION

Unlike the wide and varied selection of materials available for merely aesthetic compensation of losses, materials for strength-providing fills in wood objects fall within a narrow range of options, defined by cohesive strength and adhesive compatibility with each other, and ultimately with the wood itself. The favored system for restoring strength to a loss or break while maximizing retreatability is the use of epoxy or wood-epoxy combination to fill the gap and a thermoplastic resin or glue to act as barrier and adhesive bridge.
