Removing salt efflorescence from a plaster cast of the first part of a Maya Calendar
This is the cast in the British Museum storage. Now a hundred and twenty years old, it requires some conservation. Casts like this one are our best record of how the original monument looked, since a further century of weathering has eroded the surface of the original monument. Conservation work on the casts is therefore vital to retain details that might otherwise be lost.
