[DUMBGRUNT]

old-fashioned lime-light

No concerns about having that quicklime around the
house?

Eats flesh and bone away
It eats the brittle bone by night
And the soft flesh by day
It eats the flesh and bones by turns
But it eats the heart away
-Oscar Wilde,

[Aevery_Freeman]

Carbon rod yet called lime-light by thespians (so we make allowances) as it is designed to be a foot-light.

It was used in a theater and is quite old.
