White glue, or polyvinyl acetate (PVA) glue, is occasionally used in paleontology for non-permanent stabilization and assembly of fossils. It is favored for its ease of use, low cost, and availability. White glue can be applied to hold fossil fragments together temporarily or to secure delicate pieces during transport or initial examination. Since white glue is water-soluble, it can be easily removed, making it a reversible option for short-term stabilization. However, due to its lower strength and susceptibility to moisture, it is not typically used for long-term conservation purposes. Usage on fossiles such as shells is recommended.
