Cthulhu2 Posted March 12, 2018 Share Posted March 12, 2018 I've been collecting fossils for a while now and it finally happened, I broke one of my finds. Repair and restoration is a part of paleontology that I have no experience and could use some help! What products do you guys recommend? Link to comment Share on other sites More sharing options...
caldigger Posted March 12, 2018 Share Posted March 12, 2018 Do both parts fit together exactly or did you lose any, leaving gaps? Link to comment Share on other sites More sharing options...

caldigger Posted March 12, 2018 Share Posted March 12, 2018 How big is this piece? Are going to need to great some bracing contraption or is it manageable as a small project. Pictures will help with assessment. Link to comment Share on other sites More sharing options...

izak_ Posted March 12, 2018 Share Posted March 12, 2018 I agree pics may help but I would use normal superglue. Link to comment Share on other sites More sharing options...
TNCollector Posted March 12, 2018 Share Posted March 12, 2018 Preferably I would use a thick solution of Butvar B-76 to bond it, but superglue will work too. Link to comment Share on other sites More sharing options...
bone2stone Posted March 15, 2018 Share Posted March 15, 2018 I agree with these guys about the superglue but if you do not hit it just right you may need to "re-break" it to fit it correctly. Using some modeling clay to situate your specimen in a "fixed" position will give it a stable hold so your "fix" will be as good as it can be. The use of a water soluble glue such as "wood" glue is slower but has NEVER failed me. I even use it for a stabilizer. Thinned down and allowed to dry makes for a more stable specimen but can leave a "Sheen" that could be un-desirable. I use it to stabilize pyrite on occasion and some of my pyrite ammonites, out of the Del Rio formation, I have had over 30 years. I have even used it to stabilize ivory as well. Mastodon skull, donated to a Grand Prairie Tex High school, had this concoction used on the ivory or what was left of it. Later, while the school kids excavated it, it was further stabilized with a substance used to stabilize dry rot wood. Link to comment Share on other sites More sharing options...
