While perhaps not all BAR readers have the time and resources to replicate an Iron Age gate or Byzantine mosaic, anyone can make a mudbrick! The recipe is simple—and the ingredients common: As long as you have access to mud, water and straw (or another type of organic material), you, too, can mimic the manufacturing process used by ancient Egyptians—and Israelite slaves—to make mudbricks.
In the summer of 2013, archaeologists at Tell Timai made mudbricks to conserve the ancient walls at their site in the Nile Delta. Robert Littman, Marta Lorenzon, and Jay Silverstein describe the process in “With and Without Straw: How Israelite Slaves Made Bricks,” published in the March/April 2014 issue of BAR.
Their efforts produced great results, and although time-consuming, their procedures can be followed to create mudbricks of your own:
1. Mix topsoil and water to create a thick mud.
2. Add straw. While the composition of the mud will affect the exact proportions, as a general rule, add a half pound of straw for every cubic foot of mud mixture. If you have access to grain chaff (a byproduct of threshing), you can use that as temper. If not, chop straw into very small pieces—called straw chaff—and use that.
3. Knead the mud mixture with your bare feet for four days.
4. Once it has fermented (after four days of kneading), leave the mixture alone for a few days.
5. Knead the mixture again on the day you plan to form your mudbricks.
6. Pour the mud mixture into molds (the shape of your choosing) and let them solidify in the molds for at least 20 minutes.
7. Remove from molds and deposit on a drying floor layered with sand and straw to prevent the bricks from sticking to the floor itself.
8. Let the bricks dry for a week.
