I found it very interesting to visit this typical Punjabi Brick Factory. First because brick is a very important construction material all around the world. But second, because here you see bricks everywhere. In transport all the time on the road, on differnt vehicles: from push carts and rickshaws to horse carriages and large trucks. I also saw roadside dealers selling bricks in relatively small quantities.
Here I was shown how they first form the bricks, then dry the material in the sun and finally put it into the furnace - using coal - to finish it at temperatures between 1,000 and 1,500 degrees C.
The building around this very large super-hot furnace is also made of brick. When you stand on it you can even look through a small hole into the chamber. It's terribly hot up there. Just imagine if you have to work there with outside temperatures, in summer, of up to 45 degrees...
Then they store them and make them available to customers from small to large.
