Oh have I got pictures of rocks. Ever since taking up mineral collecting I’ve got big rocks and green rocks and glittery rocks and radioactive rocks. Some might say I’ve got rocks in my head, or that I am a rock star.
But this is a shot that I took before I met my geologist hubby. Which means, I’ve always had a thing for rock.
It is a lime kiln found near Limehouse, Ontario, which is a popular access point for the Bruce Trail.
As per the Limehouse Kiln Society, this draw or shaft kiln was probably built in the 1870s. It measures about 18 ft x 22 ft at the base and stands about 53 ft tall.
In the day when this kiln was in use, hand-crushed limestone was stacked in layers with wood or coal. The pile of rock and tinder lay on a grate above the air inlet or “eye” of the kiln. A fire was lit at the base and when the stack burnt through, the resulting lime was drawn out at the bottom. Check out what Wikipedia has to say if you’d like more science-y stuff.
