At first I thought they had sent me the wrong bricks. Before buying them I had asked them why they were so cheap, were they a normal brick, were they some unusual type of brick such as a slip? No they said. Nothing on their website and my first look at the Ibstock web indicated they were engineering non face work bricks.
This is the Huws Gray website:

The Ibstock page for these bricks is here:

But it's only when you look deeper that you find out what they really are. You need to launch the ibstock brick selector to get the full info.

Well thanks a lot Huws Gray for the lack of this information on your website and from the staff.
So now I have 400 bricks that are ideal for building something like a sewer, great!
