Pottery reconstruction allows archaeologists to better understand their artifacts and gain a more complete understanding of ancient ceramic techniques. Reconstruction techniques have evolved over time that strive for both better conservation practices and long-lasting results, as well as the use of bonding materials that are reversible rather than permanent. This poster examines the process of utilizing an acetone-based glue consisting of dissolved polymer beads of differing strength solutions. The entire process with be illustrated by step-by-step photos and directions as well as the quality of the final results. Two layers of different solution consistencies are applied to the pottery in different stages before the pieces are joined together. The first layer of glue is a thin coat made of 5% polymer and 95% acetone, and it is applied to any edges that will be refit. This layer fortifies the sherd and ensures that the glue applied is not stronger than the sherd itself. After the first layer has dried, the second coat of glue, made of 12% polymer and 88% acetone, is added to each piece. The sherds are then joined and placed in a secure location to dry, such as a bin of silica beads. Acetone-based polymer glue is strong and flexible, yet also dissolvable. Any mistakes can be unmade with the careful application of small amounts of acetone, and no restoration action is utilized on the pottery fragments that cannot be undone. This method of reconstruction is safe, secure, long-lasting, and meets modern conservation standards.
