A little more about limestone
Limestone is a natural rock made up partly from fossilised sea creatures. It’s mostly used in buildings as it’s strong but easy to work with – the famous Bath and Cotswold stones are limestone (ours is similar, just paler and less yellow).
Tumbling these tiles with pebbles, sand and water gives them a finish that’s velvety smooth – and not shiny – but that still shows their natural texture. You’ll see patches that are paler and open textured, a bit like the veins in marble.
