Tudor Roof Tiles has always made their roof tiles using the red clay called Etruria Marl.
Renowned for its superb strength, the earliest use of Etruria Marl was Roman brick making from the late 1st to 3rd century AD.
Bricks made from this clay were used as engineering bricks due to their high strength.
During the 17th century, it was found that more strength could be gained in each brick by reducing the oxygen during high temperature firing. This also caused the clay to turn from red to blue.
These bricks were known as ‘Staffordshire blue’ and have a water absorption level of approximately 4.5%.
In the 19th century Staffordshire blue bricks were used for the construction of almost every railway, road and canal bridge in the UK.
Although this clay is not the cheapest to buy, we at Tudor Tiles believe that the quality benefits it gives to our tiles far outweighs the cost.
