As the name suggests, old Chicago bricks date to the late 1800s, but they became widely used during the middle of the 20th century as Chicago grew and became one of the centers of the US industry.
Genuine Chicago brick pavers were made from lime-laced clay and baked in coal kilns. Lime gives these bricks extreme durability, which is why they lasted through more than two centuries of harsh Chicago winters. Another great thing about these bricks is that they dry quickly, which is an excellent advantage if you live in an area with frequent rainstorms. Since these bricks do well in hot and humid climates, they are a perfect solution for Florida residents. On top of that, their light color and unique appeal became strongly associated with Florida, since so many residents favor Chicago bricks as opposed to modern factory-stamped ones.
