PODMANICZKY<br>STRUCTURAL FILLS FOR LARGE WOOD OBJECTS: CONTRASTING AND COMPLEMENTARY APPROACHES<br><br>JAIC 1998, Volume 37, Number 1, Article 8 (pp. 111 to 116) <br><br><br>From the conclusion:<br><br>"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."<br><br clear="all"><br>-- <br><div class="gmail_signature"><div dir="ltr">Ian Hart<div><br></div><div>Preparator</div><div>Exhibit Studio</div><div>California Academy of Sciences</div><div>55Music Concourse Drive</div><div>Golden Gate Park</div><div>San Francisco CA 94118</div><div>(415) 379-5879 </div><div><br></div></div></div>
