Objects intended for exhibition can require extensive reconstruction to demonstrate their cultural values. Clay, which is versatile and esay to work, allows missing areas to be built up directly onto the existing ceramic without the need for moulds. With the use of techniques such as throwing and handbuilding, it can be manipulated quickly and easily, thus allowing the shape to be perfected before firing to 740 degrees C. The fired surface can be easily sanded and is compatible with fine filling materials and cold setting paint mediums. The reconstruction, which is attached to the original using a reversible adhesive, forms an inert, detachable fill that has excellent long-term ageing properties.
