How did she apply the tape?
It is important to position the tape properly when taping up joins or the fragments will not be supported and may sag. A ninety-degree angle across the join gives the greatest strength. The tape is pulled tight across the fragments. Tape is not applied over fragile areas of surface decoration, such as flaking enamels or gilding, although this is unavoidable for some small fragments. The tape can be peeled off cleanly from areas of intact glaze with the assistance of acetone. Any residues are also removed with acetone.
