[Nhcoll-l] Gap fillers

[Ian Hart]

Here is a link to a short article on approaches to structural gap filling
(applied to wood and furniture conservation) that those filling gaps in
bone may find useful:

STRUCTURAL FILLS FOR LARGE WOOD OBJECTS: CONTRASTING AND COMPLEMENTARY
APPROACHES

>From the 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."
