You Brits are so lucky. I would love to have something like this in my "backyard". Although I would not be using the quicklime to spread on a field. 10 tons of quicklime would come in handy for some restoration projects.
I was born in Amberly & my Dad worked at the chalk pits when it was still Pepper's builders merchants. My grandmother knew the last lime-burner that was based there - he had no eyebrows and no hair on the first four inches of his head - it had all been burnt off!
