Wire cut extruded bricks. For this type of brick the clay is extruded and cut by wore into individual bricks. This is a very cost effective way of producing bricks and is done by an automated production process. These bricks are readily available in a variety of styles and colors.
Stock bricks; are usually slightly more expensive than wire cut Bricks. These are a soft mud brick which are sometimes irregular in shape.
Handmade bricks; as previously discussed above, handmade bricks are very desirable and individual in shape and color. This brick is one of the most expensive sorts of brick.
Fletton or London Brick; is a brick made from clay extracted from the south east of England which contains traces of oil which is burnt off during the burning process in the kiln.
Arch and Clinker bricks This term is used for bricks which are burned immediately. They are over burnt and sometimes distorted in shape. Body, Cherry and/or hard bricks. These bricks are of a higher quality and are generally the bricks that were in the centre of the pile of bricks which have been burned. These bricks are top bricks as they have a higher overall quality and finish. Cherry is used as a term when the clay which has been used burns red.
Salmon, Pale or Soft bricks. These are the bricks which were nearer to the outside of the kiln during burning which means they are slightly under burnt. These bricks are generally softer than the bricks taken from the centre of the kiln are therefore are of a lesser quality, although this does not affect the overall shape of the brick.

Water struck Brick This type of brick is a soft mud moulded brick. It uses alluvial clay which deposited at the end of the last ice age. The clay is pressed into mould lined with silicate. When the bricks are removed from their mould, they are left with a textured effect which can only be achieved using this method. This type of brick looks old and handmade even when new.

Engineering Bricks Engineering bricks are called so due to their overall strength and water absorption. The Class A brick has strength of 125N/mm² and water absorption of less than 4.5%. Class B engineering bricks have a strength greater than 75N/mm² and water absorption of less than 7%. Traditionally used in civil engineering, these bricks are also useful for damp courses and structural design.
