We have been experimenting with our tumbling machine, our limit on the width has been around 250mm the thickness around 20mm.
To achieve a wider product we have put some 30mm material through the tumbler and the end result is the image below.

We have treated these tiles with Linseed oil, the oil enhances the colour and the fossil content.
These fossils date back to when The Peak District National Park was under warm seas some 360 million years ago. To find out more about the history of this very unique stone click here

The tumbling give the effect of aging the tiles by taking the edge of the tiles giving them a look that is very popular in larger rooms.
Limestone has some very unique properties , such as very good slip resistance as per our test results from The BRE Group who are backed by an extraordinary range of test facilities, their experts test individual materials and products, building systems, engineering structures and whole buildings, using established methods and bespoke research tests and simulations.
