Australian YouTuber Primitive Technology just posted a video, currently trending at the number one spot, showing him create mud bricks from scratch. First, we see him make a brick mold from wood, with the aim of making bricks measuring 25 x 12.5 x 7.5 cm.
“A log was split, and mortise and tenon joints were carved using a stone chisel and sharp rocks. The mold was lashed together with cane to prevent it from coming apart when used,” he writes in the video description.
Next, he made a mixture of palm fiber as a base for the bricks. This was then slapped into the mold to be shaped and then taken to the drying area, where he made up to 140 bricks. Once dry, the bricks were placed in a monolithic kiln he built himself, where they were fired for 3 hours until sufficient.
“Interestingly, the kiln got hot enough so that iron oxide containing stones began to melt out of the tiles. This is not metallic iron, but only slag (iron oxide and silica) and the temperature was probably not very high, but only enough to slowly melt or soften the stones when heated for 3 hours,” continues Primitive Technology, who doesn’t share his name publicly.
He noted that the bricks and tiles he made were weaker than objects made from regular clay, due to the silt, sand and gravel composition of the soil used.
Either way, it’s fascinating viewing for ancient history buffs.
The man behind it claims he only does this as a hobby using ancient techniques to see how far he can go without modern technology. However, he does admit to living in a modern house and eating modern food.
“I just like to see how people in ancient times built and made things. It is a good hobby that keeps you fit and doesn’t cost anything apart from time and effort,” he writes on his WordPress page.
