Using lasers to clean alabaster
Recently, the 12th-century alabaster arch to St Mary’s, Tutbury, Staffordshire was cleaned. This church has a monumental west doorway, built in the mid-12th century and richly carved with Romanesque ornament. The doorway comprises six orders or receding arches. The innermost order is formed of thirty blocks of locally-mined alabaster. Each carved with three beak-heads and a human or animal figure. Interestingly, it is the only instance of alabaster used in an exterior arch in the country.
