Abstract

The treatment of archaeological ceramics, whether on site or in the laboratory, can be effectively carried out with the use of one synthetic material, Acryloid B-72. This acrylic copolymer provides excellent properties for the strengthening or consolidation of weak and friable ceramics, and also makes an excellent adhesive. The strength and durability of B-72 make it a suitable adhesive for a broad range of ceramics, from low-fired earthenwares to china and porcelain.

Acryloid B-72 is easily prepared on site, and for most applications can be dissolved in acetone. Various concentrations are recommended and application can be modified to suit local conditions and needs. Flaking and fragile fragments can be consolidated in situ (if dry) and lifted for individual attention in the laboratory. Soluble salts may be extracted from consolidated ceramics by soaking or using poultices.

The well-known stability and reversibility of Acryloid B-72 allow for easy retreatment, or subsequent repair of additional fragments.
