1 .Test the red soil to determine if it is suitable for creating bricks. Pour water onto a handful of soil and mix until it is slightly sticky. Shape the moist soil to form a ball and leave it in the sun for two to four days. Inspect the ball to ensure it is intact, has retained its shape and is free from cracks; if so, it is suitable for bricks.
2.Mix clay with the red soil if the ball of sand cracks or crumbles due to the sun; the ideal ratio is 60-percent clay to 40-percent soil. For instance, a mix comprised of 6 lbs. of clay and 4 lbs. of soil is sufficient for 10 bricks. Use a trough if you are making a few bricks or a wheelbarrow if making many bricks.

3.Pour water into the soil and clay mixture in the trough or wheelbarrow. Mix the components slowly with a trowel. The mixture should be soft enough to fill the mold, but firm enough to hold its shape. Add more soil to the mixture if you make it too soft, or pour in some water to soften the consistency.

4Pour the mixture into your desired molds. If you are using a row mold, pour the mix into the separate cells quickly so the bricks are ready at the same time.

5Place the molds in a spot exposed to full sunlight for 30 to 40 minutes if you live in a tropical climate. Turn the molds out into drying racks and leave them in the sun for six months or longer, until the edges turn white. Alternatively, place the drying racks in a kiln preheated to 1,800 degrees Fahrenheit. Leave the bricks for a week, then lower the temperature by half before removing the prepared bricks.
