Etruria Marl

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.

  1. It’s great to see traditional materials still being used – in the age of rubber roofing and tiles which appear to be one material but are actually made of another, authenticity has a part to play in people’s design and buying decisions. Clay with origins in the 1st century will certainly capture that market – not to mention their excellent strength qualities and genuinely contribution to a great quality roof. The roofing market needs variation so it’s excellent to hear that we’re still passionate about the old way of doing things.
