ST20 very old quarry tiles (Gnosall ST20)

A very long time ago, someone took up quarry tiled flooring a chucked in the garden and was subsequently buried. I dug them up and saved the intact ones.
They are classic orange/rust in colour and some are black/dark grey.
Majority 6” (15cm) square and some thicker than others.
They would be great relaid but obviously not got enough you do a large area.
