Question 1

1. What are stock bricks?

Accepted Answer

Stock bricks are soft-moulded clay facing bricks made by pressing clay into sanded moulds, creating a textured and slightly irregular surface. They’re defined by their softer arrises, natural creasing, and variation in colour, which result from the traditional manufacturing process. In the UK, stock brick is commonly associated with London stock brick, including the well-known yellow stock bricks used across historic and modern masonry.

Question 2

2. How many stock bricks come in a pallet?

Accepted Answer

A standard UK pallet typically holds around 400 to 500 65mm stock bricks. This depends on the manufacturer and format though, and pallets can come with fewer than 300 or more than 600 bricks. Check with the retailer or manufacturer if you're unsure how many you’re getting.

Question 3

3. What size are stock bricks?

Accepted Answer

Most modern stock bricks follow the standard UK brick size of 215 x 102.5 x 65mm, with some variation for handmade products.

Question 4

4. Are all stock bricks yellow?

Accepted Answer

No, not all stock bricks are yellow. While many people associate stock bricks with the pale tones of London stock brick, this is only one variation. The yellow colour comes from local clay with chalk and lime, which produces buff or yellow tones when fired.

Stock bricks are available in a wide range of colours, including red, brown, and multi-toned finishes. These differences depend on the clay composition and firing process used during manufacture.

For example, red stock bricks are also common, particularly where clay contains higher levels of iron oxide. In some historic builds, red stocks were used for side and rear walls, with yellow stock bricks used on the front elevation.

Question 5

5. Are reclaimed stock bricks suitable for reuse?

Accepted Answer

Yes, reclaimed stock bricks can be reused if cleaned and checked. They’re especially appropriate for matching existing work or conservation projects, although may not be as durable as modern bricks.
