My walk around the Rhug Estate reminded me of the phrase "In the
limelight." This saying had its origin in the theatre world before the invention of electricity. The stage would be lit by heating a block of
quicklime (Calcium Oxide or CaO), which was set in special containers on the stage. This lime had its origin in
lime kilns, and the disused remains of some of these can be found on the Rhug Estate. The most common use was in converting limestone into fertiliser.
