Young Brunette Girl With Blue Eyes Reveals Her Dress On The Old Iron Bench In The Room With Brick Walls

Some brickmakers create innovative sizes and shapes for bricks used for plastering (and therefore not visible) where their inherent mechanical properties are more important than the visual ones. These bricks are usually slightly larger, but not as large as blocks and offer the following advantages:
• a slightly larger brick requires less mortar and handling (fewer bricks) which reduces cost
• ribbed exterior aids plastering
• more complex interior cavities allow improved insulation, while maintaining strength.
